“…From literature, 67,68 it is hypothesized that the unique surface morphology of the footpad is not only responsive to interactions with external stimuli but also has great potential for biosensing due to its ability to adhere with living cells or tissues. Theories were developed to support the hypothesis, yet no experiment validations were presented.…”

Hierarchical assembly architectures of functional polymer particles are promising because of their physicochemical and surface properties for multi‐labeling and sensing to catalysis and biomedical applications. While polymer nanoparticles’ interior is mainly made up of the cross‐linked network, their surface can be tailored with soft, flexible, and responsive molecules and macromolecules as potential support for the controlled particulate assemblies. Molecular surfactants and polyelectrolytes as interfacial agents improve the stability of the nanoparticles whereas swellable and soft shell‐like cross‐linked polymeric layer at the interface can significantly enhance the uptake of guest nano‐constituents during assemblies. Besides, layer‐by‐layer surface‐functionalization holds the ability to provide a high variability in assembly architectures of different interfacial properties. Considering these aspects, various assembly architectures of polymer nanoparticles of tunable size, shapes, morphology, and tailored interfaces together with controllable interfacial interactions are constructed here. The microfluidic‐mediated platform has been used for the synthesis of constituents polymer nanoparticles of various structural and interfacial properties, and their assemblies are conducted in batch or flow conditions. The assemblies presented in this progress report is divided into three main categories: cross‐linked polymeric network's fusion‐based self‐assembly, electrostatic‐driven assemblies, and assembly formed by encapsulating smaller nanoparticles into larger microparticles.

This paper presents the multi-directional vibration behaviors of buckled viscoelastic nanoribbons based on the nonlocal theory containing scale effect, where the Lagrange’s motion equation is introduced to construct the nonlocal viscoelastic governing equation. The first-order transverse vibration mode and the first-order longitudinal vibration mode are considered to study the influences of the scale characteristics on the natural frequency of two different vibration modes. The Kelvin–Voigt model is used to characterize the material viscoelastic property, and an analytical method is presented to solve the nonlocal viscoelastic vibration behaviors of the buckled nanoribbon containing scale effect. Results show that the scale effect could decrease the natural frequency of buckled nanoribbon with viscoelastic behavior, as well as the half bandwidth during forced vibration. The presented results may be taken as a useful reference for the fabrications and applications of buckled nanostructures-based sensors & actuators, electronics, energy harvesters, etc.
