Natural structural materials,such as spider silk,wood,and bone,are universally acknowledged as the gold standard for the ideal combinations of strength and toughness.The exceptional integrated performance of these biological materials can be ascribed to their multiscale hierarchical architectures and components.Mimicking the hierarchical assembly feature of natural materials,artificial fibers,which are generated through the one-dimensional(1D)assembly of nanowires,have been widely reported with remarkable flexibility and functionality.Furthermore,the distinguishing feature of nanowires’1D assembly can bridge the unique properties of nanowires with their potential functional applications.This tutorial review summarizes the recent developments in the assembly of nanowires into macroscopic 1D fibers in the liquid state.We begin by introducing the general strategies and mechanisms for assembling nanowires in one direction and then,illustrate their potential applications in energy storage,sensors,biomedical engineering,etc.Finally,a brief summary and some personal perspectives on the future research directions of nanowires’1D assembly are also proposed.

Since the ferromagnetic(Fe_(3)O_(4))nanoparticles were firstly reported to exert enzyme-like activity in 2007,extensive research progress in nanozymes has been made with deep investigation of diverse nanozymes and rapid development of related nanotechnologies.As promising alterna-tives for natural enzymes,nanozymes have broadened the way toward clinical medicine,food safety,environmental monitoring,and chemical production.The past decade has witnessed the rapid development of metal-and metal oxide-based nanozymes owing to their remarkable physicochemical proper-ties in parallel with low cost,high stability,and easy storage.It is widely known that the deep study of catalytic activities and mechanism sheds sig-nificant influence on the applications of nanozymes.This review digs into the characteristics and intrinsic properties of metal-and metal oxide-based nanozymes,especially emphasizing their catalytic mechanism and recent applications in biological analysis,relieving inflammation,antibacterial,and cancer therapy.We also conclude the present challenges and provide insights into the future research of nanozymes constituted of metal and metal oxide nanomaterials.

Metal-organic frameworks(MOFs)have attracted widespread interest due to their unique and unprecedented advantages in microstructures and properties.Besides,surface-enhanced Raman scattering(SERS)technology has also rapidly developed into a powerful fingerprint spectroscopic technique that can provide rapid,non-invasive,non-destructive,and ultra-sensitive detection,even down to single molecular level.Consequently,a considerable amount of researchers combined MOFs with the SERS technique to further improve the sensing performance and broaden the applications of SERS substrates.Herein,representative synthesis strategies of MOFs to fabricate SERS-active substrates are summarized and their applications in ultra-sensitive biomedical trace detection are also reviewed.Besides,relative barriers,advantages,disadvantages,future trends,and prospects are particularly discussed to give guidance to relevant researchers.

User-interactive electronic skin(e-skin) that could convert mechanical stimuli into distinguishable outputs displays tremendous potential for wearable devices and health care applications. However, the existing devices have the disadvantages such as complex integration procedure and lack of the intuitive signal display function. Here, we present a bioinspired user-interactive e-skin, which is simple in structure and can synchronously achieve digital electrical response and optical visualization upon external mechanical stimulus. The e-skin comprises a conductive layer with a carbon nanotubes/cellulose nanofibers/MXene nanohybrid network featuring remarkable electromechanical behaviors, and a stretchable elastomer layer, which is composed of silicone rubber and thermochromic pigments. Furthermore, the conductive nanohybrid network with outstanding Joule heating performance can generate controllable thermal energy under voltage input and then achieve the dynamic coloration of silicone-based elastomer. Especially, such an innovative fusion strategy of digital data and visual images enables the e-skin to monitor human activities with evermore intuition and accuracy. The simple design philosophy and reliable operation of the demonstrated e-skin are expected to provide an ideal platform for next-generation flexible electronics.

Passive and label-free microfluidic devices have no complex external accessories or detection-interfering label particles.These devices are now widely used in medical and bioresearch applications,including cell focusing and cell separation.Geometric structure plays the most essential role when designing a passive and label-free microfluidic chip.An exquisitely designed geometric structure can change particle trajectories and improve chip performance.However,the geometric design principles of passive and label-free microfluidics have not been comprehensively acknowledged.Here,we review the geometric innovations of several microfluidic schemes,including deterministic lateral displacement(DLD)inertial microfluidics(IMF),and viscoelastic microfluidics(VEM),and summarize the most creative innovations and design principles of passive and label-free microfluidics.We aim to provide a guideline for researchers who have an interest in geometric innovations of passive label-free microfluidics.

Objective:Although great progress has been made in the field of siRNA gene therapy,safe,efficient,and targeted delivery of siRNA are still major challenges in siRNA therapeutics.Methods:We developed an up-conversion nanoparticle-based nanocage system.This system protected the siRNA from being degraded by nucleases in organisms and selectively delivered the siRNAs to the tumor sites,due to modifications of targeted molecules on the surfaces of nanocages and local inhalation.Results:The siRNAs delivered by the up-conversion nanoparticle nanocages were protected from degradation in transit to the tumor sites,where they accumulated.Compared with the passive target and control groups,the up-conversion nanoparticles based on the nanocage system showed a tumor suppressive effect after approximately 3 weeks of treatment.Conclusions:The up-conversion nanoparticle nanocages efficiently delivered vascular endothelial growth factor siRNAs to tumor sites.Mice with lung tumors treated with tumors targeting up-conversion nanoparticle nanocages showed steady body weight changes,high tumor inhibition ratios,and longer survival times.

The tunable mid-infrared source in a broad-spectrum heralds great scientific implications and remains a challenge.Nanolocalized catalytic combustion facilitates access to customizable infrared light sources.Here,we report on fabricating platinumalumina bilayer nano-cylinder arrays for methanol catalytic combustion,which enables them to act as an array of infrared point light sources,with wavelength tunable by controlling the flow rate of methanol/air mixture.We then propose a technique of integrating nanophotonic structures with catalytic combustion to engineer infrared light emission.We demonstrate a prototype of a topological photonic crystal catalyst array in which infrared emission can be enhanced significantly with highly vertical emission.This work establishes a framework of nanophotonic catalytic combustion for infrared light sources.

In this research,we design and implement a small,convenient,and noninvasive paper-based microfluidic sweat sensor that can simultaneously detect multiple key biomarkers in human sweat.The origami structure of the chip includes colorimetric and electrochemical sensing regions.Different colorimetric sensing regions are modified with specific chromogenic reagents to selectively identify glucose,lactate,uric acid,and magnesium ions in sweat,as well as the pH value.The regions of electrochemical sensing detect cortisol in sweat by molecular imprinting.The entire chip is composed of hydrophilically and hydrophobically treated filter paper,and 3D microfluidic channels are constructed by using folding paper.The thread-based channels formed after the hydrophilic and hydrophobic modifications are used to control the rate of sweat flow,which in turn can be used to control the sequence of reactions in the differently developing colored regions to ensure that signals of the best color can be captured simultaneously by the colorimetric sensing regions.Finally,the results of on-body experiments verify the reliability of the proposed sweat sensor and its potential for the noninvasive identification of a variety of sweat biomarkers.
