Biomimetic Infiltrating Surface Construction Based on Micro and Nano Structures

Abstract

Microfluidic chips hold significant potential for applications in various fields, such as biological analysis, chemical separation, and drug screening. Here, we draw inspiration from the natural ability of aquatic plants to capture different substances in streams, focusing on the design and fabrication of surfaces with micron and nano-scale structures to mimic the wetting phenomenon observed in nature, thereby achieving the capture and separation of specific substances. This paper reports on the self-assembly of magnetic nanoparticles, the preparation of flexible magnetic nano-chains, and the modification of microfluidic chip surfaces, providing a novel perspective and approach to microfluidic chip technology.
