Abstract: In this work, we prepared surface molecularly imprinted polymer (MIP) for selective recognition of pneumocandin B0 (PNB0). Methacrylic acid (MAA) was first grafted onto silica gel particles (SiO2) in the manner of "grafting from" by using 3-methacryloxypropyl trimethoxysilane as intermedium, and then PNB0 molecules were imprinted on the surface of the obtained particles in the presence of ethylene glycol diglycidyl ether as the cross-linker. The prepared MIP-PMAA/SiO2 was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and thermo-gravimetric analysis, which confirmed the successful grafting of MAA onto SiO2 and the grafting degree was calculated to be 12.50 wt%. The binding properties of the products were investigated and it is found that the binding process of PNB0 followed the pseudo-second-order kinetic model. The as-prepared material also displays relatively quick adsorption kinetics and decent recognition affinity toward the template over its structurally related compound
