A wide variety of polymer materials, with the advantages of convenient processing and molding, low raw material cost, very suitable for mass production, currently the most widely used, COC and COP have good optical and chemical properties, but the price is high; PDMS materials can be moulded with silicon or SU8



Silicon material has good chemical inertness and thermal stability, and complex two-dimensional or three-dimensional microstructures can be reproduced with high precision by photolithography or etching methods



The glass chip has many advantages, such as good light transmittance and electropermeability, low fluorescence background, high mechanical strength, small thermal deformation of microchannel and easy modification of channel surface
