Green molecularly imprinted polymers for sustainable sample preparation

15 Pág. Departamento de Medio Ambiente y Agronomía​ (INIA)The use of molecularly imprinted polymers in sample preparation as selective sorbent materials has received great attention during the last years leading to analytical methods with unprecedented selectivity. However, with the progressive implementation of Green Analytical Chemistry principles, it is necessary to critically review the greenness of synthesis and further use of molecularly imprinted polymers in sample preparation. Accordingly, in the present review, the different steps and strategies for the preparation of molecularly imprinted polymers, the used reagents, as well as their incorporation to microextraction techniques are reviewed from a green perspective and recent alternatives to make the use of molecularly imprinted polymers more sustainable are provided.This article is based upon work from the National Thematic Network on Sample Treatment (RED-2018-102522-T) funded by the Spanish Ministry of Science, Innovation and Universities, and the Sample Preparation Study Group and Network, supported by the Division of Analytical Chemistry of the EuropeanPeer reviewe
