Using the conducting polymers, it is possible to design sensitive and biologically compatible biosensors. Nowadays the best-known and the most common biosensors are amperometric glucose biosensors. They can detect blood’s free glucose in a short amount of time – it is very important for people with diabetes. The active part of the biosensor is glucose oxidase (GOx) enzyme immobilized on the surface of the electrode. The conducting polymers are used as a matrix for immobilization that facilitates electrons transfer from enzyme to electrically conductive surface of the electrode. When constructing biosensor, one of the most important aims is to create enzyme and polymer system, which would ensure the thermal stability and retain the catalytic activity of the enzyme. The main goal...

The synthesis of core–shell microparticles containing nested sets of dispersed metal and polymer micro‐ and nanoparticles is achieved through in situ photopolymerization using a double co‐axial capillaries microfluidic device. The flow rates of the carrier, shell, and core phases are optimized to control particle size and result in stable core–shell particles with well‐dispersed three‐level composites in the shell matrix. The robustness and reversibility of these core–shell particles are demonstrated through five cycles of drying and re‐swelling, showing that the size and structure of core–shell particles remain unchanged. Additionally, the permeability and mobility of dye molecules within the shell matrix are tested and showed that different molecular weight dyes have different penetration times. This study highlights the potential of microfluidics as a powerful tool for the controlled and precise synthesis of complex structured materials and demonstrates the versatility and potential of these core–shell particles for sensing applications as particle‐based surface‐enhanced Raman scattering (SERS).
