Title: 
Bioinspired Materials Processing and Sensing
Abstract: Processing multifunctional materials with desired properties is pivotal for technological advancements in sectors including the healthcare, sensing technologies, and defense. Each application typically necessitates a unique and precisely defined set of material properties, tailored to its specific functional and performance requirements. We have used a hydrodynamic spinning strategy to manufacture polymer microstructures with desired properties. This approach represents a paradigm shift from current methods of manufacturing microstructures, offering a bioinspired, versatile process with precise material formulations and processing parameters. We have demonstrated the ability to tailor the shape and size of biocompatible microstructures on demand using hydrodynamic spinning.
In our hydrodynamic spinning approach, microstructures are formed using a coaxial flow of pre-polymer and crosslinking agents in a microchannel. Microstructures can be produced on multiple length scales with a wide variety of shapes using various polymer chemistries and material compositions. The length scale can be adjusted from tens to several hundreds of micrometers by controlling the ratio of core and sheath flow rates, solutions viscosities, and channel dimensions. The ability to produce uniform, monodisperse microstructures with tailored morphological, structural, thermal, and chemical features opens up possibilities for emerging technologies.
