Problems solved by technology

[0003] The matrix of molecularly imprinted materials can be inorganic materials, such as silica gel, alumina, etc., or polymer materials, but most of the recognition sites of polymer microspheres are inside the polymer microspheres. When recognizing larger molecules, the diffusion resistance The presence of will make it difficult for the molecule to be recognized to bind to the recognition site
