Highly selective and responsive detection of simetryn in tobacco samples based on molecularly imprinted photonic crystal hydrogels

A novel sensor was developed based on the combination of photonic crystal templating and molecular imprinting technique (MIT) for the detection of simetryn in tobacco samples. The molecularly imprinted photonic crystal hydrogels (MIPHs) was prepared with methacrylic acid (MAA) as monomers, ethylene...
