Resumo

Molecularly imprinted polymers are advanced recognition materials selectively rebinding a target molecule present during the synthesis of the polymer matrix. It is commonly understood that the templating process is based on embedding the complex formed between a template and functional monomers into a co-polymer matrix. This happens by a polymerization of the complex with a crosslinker while maintaining their spatial arrangement forming a molecular imprint. Template removal then leads to synthetic recognition sites ready to selectively rebind their targets, which are complementary in functionality, size and shape to the target. In this study, an innovative theoretical concept using fully atomistic molecular dynamics simulations for modeling molecular templating processes is introduced yielding virtually imprinted polymers (VIPs). VIPs created for the template 17-b-estradiol and applied in modeled chromatography experiments demonstrated selectivity for their template. This evidenced the creation of virtual imprints as a result of a templated synthesis protocol, which represents a theoretical confirmation of the governing imprinting theory. (AU)
