“…properties such as high stability, strength, and flexibility, but also allow for the microscale construction of the designed surface profiles with high uniformity. In general, rationally designed micropatterns are fabricated using top-down processes including photolithography, [45][46][47][48][49] reactive ion etching, and e-beam evaporation [65] and can act as molds for elastomers (e.g., soft lithography). [66][67][68] Despite their high quality (i.e., precise patternability and process reproducibility), micropatterns fabricated by top-down processes have several drawbacks.…”

“…[8,9,11,14,16,17,20,22] Although the individual components generally exhibit elevated specific surface area and roughness, based on their unique main function and shape, the building blocks of physically engineered hierarchical structures can be classified into five groups, namely rationally designed micropatterns, wrinkles, fibers, ordered nanopatterns, and random structures. Rationally designed micropatterns are used to tune substrate mechanical characteristics or impart the designed surface profile with uniformity (i.e., sample-to-sample variation), [43][44][45][46][47][48][49][50] while wrinkles can provide increased specific surface area and roughness with high robustness or stretchable highly dense curved structures. [51][52][53] Fibers (i.e., high-aspectratio pillars) are used to increase the active specific surface area and thus strengthen chemical reactions or van der Waals forces acting on the contact surface.…”

The high demand for micro/nano hierarchical structures as components of functional substrates, bioinspired devices, energy‐related electronics, and chemical/physical transducers has inspired their in‐depth studies and active development of the related fabrication techniques. In particular, significant progress has been achieved in hierarchical structures physically engineered on surface, which offer the advantages of wide‐range material compatibility, design diversity, and mechanical stability, and numerous unique structures with important niche applications have been developed. This review categorizes the basic components of hierarchical structures physically engineered on surface according to function/shape and comprehensively summarizes the related advances, focusing on the fabrication strategies, ways of combining basic components, potential applications, and future research directions. Moreover, the physicochemical properties of hierarchical structures physically engineered on surface are compared based on the function of their basic components, which may help to avoid the bottlenecks of conventional single‐scale functional substrates. Thus, the present work is expected to provide a useful reference for scientists working on multicomponent functional substrates and inspire further research in this field.This article is protected by copyright.

The field of microfluidics encompasses the study of fluid behavior within micro-channels and the development of miniature systems featuring internal compartments or passageways tailored for fluid control and manipulation. Microfluidic devices capitalize on the unique chemical and physical properties exhibited by fluids at the microscopic scale. In contrast to their larger counterparts, microfluidic systems offer a multitude of advantages. Their implementation facilitates the investigation and utilization of reduced sample, solvent, and reagent volumes, thus yielding decreased operational expenses. Owing to their compact dimensions, these devices allow for the concurrent execution of multiple procedures, leading to expedited experimental timelines. Over the past two decades, microfluidics has undergone remarkable advancements, evolving into a multifaceted discipline. Subfields such as organ-on-a-chip and paper-based microfluidics have matured into distinct fields of study. Nonetheless, while scientific progress within the microfluidics realm has been notable, its translation into autonomous end-user applications remains a frontier to be fully explored. This paper sets forth the central objective of scrutinizing the present research paradigm, prevailing limitations, and potential prospects of customizable microfluidic devices. Our inquiry revolves around the latest strides achieved, prevailing constraints, and conceivable trajectories for adaptable microfluidic technologies. We meticulously delineate existing iterations of microfluidic systems, elucidate their operational principles, deliberate upon encountered limitations, and provide a visionary outlook toward the future trajectory of microfluidic advancements. In summation, this work endeavors to shed light on the current state of microfluidic systems, underscore their operative intricacies, address incumbent challenges, and unveil promising pathways that chart the course toward the next frontier of microfluidic innovation.
