Unlocking the potential of transdermal drug delivery
Li, Shuang, Jianhao Wu, Xiangjun Peng, and Xi-Qiao Feng
ABSTRACT
Transdermal drug delivery (TDD) has gained clinical approval over several decades, with extensive research dedicated to novel drug and device development. Despite notable research progress, the market adoption of TDD devices has not met anticipated levels, with oral administration and injection remaining predominant delivery methods. To maximize the potential of TDD, we identify bottlenecks hindering its widespread clinical application and propose promising research avenues. We begin by analyzing stringent demands necessary to truly benefit patients, addressing significant challenges in biomechanics, nanomedicine, and flexible electronics. Subsequently, we delve into skin anatomy, enhancement strategies, nano-carriers, and their underlining mechanisms, highlighting the importance and framework of quantitative modeling. Based on these discussions, we highlight the core strength of TDD, such as automatic precise administration based on feedback and high delivery efficiencies, especially applicable to localized conditions (e.g., central nervous system diseases, tumors). Finally, we envision the future of intelligent TDD device and its operation scenario, aiming to steer research efforts toward faster translation of laboratory innovations into widely used products for sufferers.

Hua, Chen, Jianye Gao, and Jing Liu
ABSTRACT
Self-healing materials span diverse application fields, including flexible electronics, soft robotics, and energy devices. However, conventional self-healing materials pose a challenge in achieving the delicate balance between flexibility and electrical conductivity. Moreover, they also suffer from prolonged healing times, incomplete healing, and high manufacturing costs. Liquid metals possess excellent self-healing capabilities owing to their unique combination of fluidic and metallic properties, high surface tension, and reversible solid-liquid phase change at room temperature, offering an intriguing material option for addressing the challenges associated with flexibility and electrical conductivity. In this review article, we comprehensively examine the domain of self-healing liquid metals from the standpoint of typical mechanisms underlying self-healing processes, as well as practical strategies employed for achieving such rejuvenation. Additionally, we explore representative applications that showcase the potential of these materials while aiming to provide a valuable reference for advancing and enhancing the field of self-healing materials. Future prospect along this direction is made.

Therapeutic potentials of peptide-derived nanoformulations in atherosclerosis: present status and future directions
Liu, Xue, Weijiao Wang, Qiang Li, Hongtao Niu, and Weili Zhang
ABSTRACT
Atherosclerosis is a severe cardiovascular disease followed by the accumulation of atherosclerotic plaques within the lumen of blood vessels resulting in reduced blood flow thus initiating a series of events. Conventional therapies for atherosclerosis encounter multiple challenges, especially difficulty in precisely concentrating in certain affected regions and the potential for unwanted side effects. Consequently, scientists are focused on developing nanoformulations for atherosclerosis diagnosis and therapy. Peptide-based nanomedicines improve conventional therapies by offering improved structural and therapeutic stability and enabling target-specific delivery. Their inherent biocompatibility and biodegradability additionally render them desirable materials intended for in vivo use. This review manuscript aims to provide an in-depth overview of peptide-based nanomedicines for atherosclerosis, focusing on targeted cells like endothelial cells, macrophages, and monocytes and their interaction with different plaque components. Moreover, the manuscript also highlights the latest progress in multimodal techniques and provides a comprehensive overview of limitations associated with their practical implementation.

Qing, Xinlin, Yunlai Liao, Yihan Wang, Binqiang Chen, Fanghong Zhang, and Yishou Wang
ABSTRACT
Composite materials have been widely used in many industries due to their excellent mechanical properties. It is difficult to analyze the integrity and durability of composite structures because of their own characteristics and the complexity of load and environments. Structural health monitoring (SHM) based on built-in sensor networks has been widely evaluated as a method to improve the safety and reliability of composite structures and reduce the operational cost. With the rapid development of machine learning, a large number of machine learning algorithms have been applied in many disciplines, and also are being applied in the field of SHM to avoid the limitations resulting from the need of physical models. In this paper, the damage monitoring technologies often used for composite structures are briefly outlined, and the applications of machine learning in damage monitoring of composite structures are concisely reviewed. Then, challenges and solutions for quantitative damage monitoring of composite structures based on machine learning are discussed, focusing on the complete acquisition of monitoring data, deep analysis of the correlation between sensor signal eigenvalues and composite structure states, and quantitative intelligent identification of composite delamination damage. Finally, the development trend of machine learning-based SHM for composite structures is discussed.

Recycling strategies for vitrimers
Zhang, Haochuan, Jingjing Cui, Guang Hu, and Biao Zhang
ABSTRACT
Vitrimer is a new type of material that combine the advantages of thermoplastic and thermoset materials. The rapid dynamic exchange reactions at high temperature allow the topology of cross-linked networks to change and rearrange while keeping material structures and properties intact. The concept of vitrimer has emerged to provide a viable strategy for the recycling of high-performance polymer materials, and lots of research works have been carried out for the development of various types of vitrimers. In addition, the recycling strategies for vitrimers are particularly important to determine the performance and potential applications of the recovered materials. Therefore, it is an innovative and valuable perspective to discuss vitrimer materials according to their different recycling strategies. In this review, we start with a brief overview of vitrimers, and then, focus on recycling strategies for vitrimers. Specifically, we highlight the advantages and disadvantages of the two different recycling strategies: physical and chemical recycling methods, and then explore the feasibility of upcycling vitrimers using 3D printing technology. Finally, the impact of recycling strategies on vitrimer materials and the prospects for maximizing the use of vitrimer materials are discussed.

Size-dependent vibrations and waves in piezoelectric nanostructures: a literature review
Zhao, Zinan, Jun Zhu, and Weiqiu Chen
ABSTRACT
With the development and applications of nano-electro-mechanical systems, academic interest in the mechanical behavior of piezoelectric structures at nanoscale is increasing. Interesting unconventional phenomena have been observed either experimentally or through molecular dynamics simulation. The most common and also important one is the size-dependent characteristics. Classical continuum mechanics with necessary modifications has been proven to be very powerful in explaining these particular characteristics in a relatively simple theoretical framework. This article reviews the recent advances in understanding the size-dependent dynamic responses of piezoelectric nanostructures from the viewpoint of modified continuum mechanics. Particular attentions are paid to three advanced theories of piezoelectricity (e.g. gradient piezoelectricity, surface piezoelectricity, and nonlocal piezoelectricity) and their abilities to predict unconventional vibration and wave characteristics in piezoelectric structures and devices at the nanoscale. The article could serve as a useful reference for the future research on or design of nanostructures with multifield couplings.

Failure mechanisms in flexible electronics
Zhao, Zhehui, Haoran Fu, Ruitao Tang, Bocheng Zhang, Yunmin Chen, and Jianqun Jiang
ABSTRACT
The rapid evolution of flexible electronic devices promises to revolutionize numerous fields by expanding the applications of smart devices. Nevertheless, despite this vast potential, the reliability of these innovative devices currently falls short, especially in light of demanding operation environment and the intrinsic challenges associated with their fabrication techniques. The heterogeneity in these processes and environments gives rise to unique failure modes throughout the devices’ lifespan. To significantly enhance the reliability of these devices and assure long-term performance, it is paramount to comprehend the underpinning failure mechanisms thoroughly, thereby enabling optimal design solutions. A myriad of investigative efforts have been dedicated to unravel these failure mechanisms, utilizing a spectrum of tools from analytical models, numerical methods, to advanced characterization methods. This review delves into the root causes of device failure, scrutinizing both the fabrication process and the operation environment. Next, We subsequently address the failure mechanisms across four commonly observed modes: strength failure, fatigue failure, interfacial failure, and electrical failure, followed by an overview of targeted characterization methods associated with each mechanism. Concluding with an outlook, we spotlight ongoing challenges and promising directions for future research in our pursuit of highly resilient flexible electronic devices.

Liquid crystal elastomer composites for soft actuators
Sun, Jianbo, Chao Wang, Yongjiao Liu, Xudong Liang, and Zhijian Wang
ABSTRACT
Liquid crystal elastomers are active materials that combine the anisotropic properties of liquid crystals with the elasticity of polymer networks. The LCEs exhibit remarkable reversible contraction and elongation capabilities in response to external stimuli, rendering them highly promising for diverse applications, such as soft robotics, haptic devices, shape morphing structures, etc. However, the predominant reliance on heating as the driving stimulus for LCEs has limited their practical applications. This drawback can be effectively addressed by incorporating fillers, which can generate heat under various stimuli. The recent progress in LCE composites has significantly expanded the application potential of LCEs. In this minireview, we present the design strategies for soft actuators with LCE composites, followed by a detailed exploration of photothermal and electrothermal LCE composites as prominent examples. Furthermore, we provide an outlook on the challenges and opportunities in the field of LCE composites.

Confined gas transport in low-dimensional materials
Duan, Hongwei, Zeyu Zhuang, Jing Yang, Shengping Zhang, and Luda Wang
ABSTRACT
Gas transport under confinement exhibits a plethora of physical and chemical phenomena that differ from those observed in bulk media, owing to the deviations of continuum description at the molecular level. In biological systems, gas channels play indispensable roles in various physiological functions by regulating gas transport across cell membranes. Therefore, investigating gas transport under such confinement is crucial for comprehending cellular physiological activities. Moreover, leveraging these underlying mechanisms can enable the construction of bioinspired artificial nanofluidic devices with tailored gas transport properties akin to those found in biological channels. This review provides a comprehensive summary of confined gas transport mechanisms, focusing on the unique effects arising from nanoconfinement. Additionally, we categorize nanoconfinement spaces based on dimensionality to elucidate their control over gas transport behavior. Finally, we highlight the potential of bioinspired smart gas membranes that mimic precise modulation of transportation observed in organisms. To conclude, we present a concise outlook on the challenges and opportunities in this rapidly expanding field.

Bioinspired ionic control for energy and information flow
Peng, Puguang, Han Qian, Jiajin Liu, Zhonglin Wang, and Di Wei
ABSTRACT
The control of ion transport by responding to stimulus is a necessary condition for the existence of life. Bioinspired iontronics could enable anomalous ion dynamics in the nanoconfined spaces, creating many efficient energy systems and neuromorphic in-sensor computing networks. Unlike traditional electronics based on von Neumann computing architecture, the Boolean logic computing based on the iontronics could avoid complex wiring with higher energy efficiency and programmable neuromorphic logic. Here, a systematic summary on the state of art in bioinspired iontronics is presented and the stimulus from chemical potentials, electric fields, light, heat, piezo and magnetic fields on ion dynamics are reviewed. Challenges and perspectives are also addressed in the aspects of iontronic integrated systems. It is believed that comprehensive investigations in bioinspired ionic control will accelerate the development on more efficient energy and information flow for the futuristic human-machine interface.

Electric-double-layer-gated 2D transistors for bioinspired sensors and neuromorphic devices
Lin, Xiangde, Yonghai Li, Yanqiang Lei, and Qijun Sun
ABSTRACT
Electric double layer (EDL) gating is a technique in which ions in an electrolyte modulate the charge transport in an electronic material through electrical field effects. A sub-nanogap capacitor is induced at the interface of electrolyte/semiconductor under the external electrical field and the capacitor has an ultrahigh capacitance density (~µF cm−2). Recently, EDL gating technique, as an interfacial gating, is widely used in two-dimensional (2D) crystals for various sophisticated materials characterization and device applications. This review introduces the EDL-gated transistors based on 2D materials and their applications in the field of bioinspired optoelectronic detection, sensing, logic circuits, and neuromorphic computation.
