Abstract: This paper reviewed the concept, history and principle of molecular inprinting and its aplication in seperation ,catalysis and sensor. There are some problems in preparation of molecular in-printin polymers with traditional method,so a new method -dispersion polymerization has been discussed . The paper presents characters of several methods to prepare polymer particles and advantages of dispersion polymerization . At the end of the paper ,it discuss some possible difficulties in appllica-tion. Template and target information:Review - MIPs and particles
