This paper reports the preparation of high density imprinted layer-coated silica nanoparticles toward selective recognition and fast enrichment of chlorpyrifos (CP) from complicated matrices. The molecularly imprinted polymers (MIPs) were successfully coated at the surface of modified silica through using the chemical immovable vinyl groups at the nanoparticles’ surface, followed by the graft copolymerization...
This paper reports the molecularly imprinted layer-coated silica nanoparticles toward highly selective separation of active diosgenin (DG) from the crude extracts of Dioscorea nipponica Makino (DNM). It has been demonstrated that DG templates were efficiently imprinted into the silica layer by the use of thermally cleavable urethane bonds between DG and 3-isocyanatopropyltriethoxysilane (IPTS), which...
