Sensors based on permeation through the polymer

A number of approaches have been reported towards forming molecularly imprinted polymer membranes, which are intended to selectively transport the 

Biomimetic electrochemical sensors based on molecular imprinting 

In Piletsky s latest work, free-standing membranes are formed by polymerisation between two glass slides, with oligourethane acrylate being incorporated in the polymer mixture to lend extra flexibility [94,95]. Using atrazine again as the imprinted species, a detection limit for atrazine of 5 nM and 20-fold selectivity over simazine are reported.
