Biomicrofluidics, a burgeoning field of research, leverages biomaterials and nature-inspired designs to create miniaturized biomimetic reactors that have applications across various areas of chemistry. The focus of the project is to develop a biomimetic microfluidic device composed entirely of biodegradable biopolymers derived from the bamboo plant. The chemical properties of bamboo’s vascular bundles are harnessed in this process. Additionally, the network of microchannels will be coated with metallic nanoparticles possessing catalytic properties through flow organic synthesis. The fabrication of a biological microfluidic device functionalized with metals paves the way for developing a new class of biomimetic bamboo microreactors. These innovative microreactors are not only more cost-effective but also more sustainable than the artificially constructed microfluidic systems currently available in the market.
