Supercritical CO2–Driven Design of Beryllium Molecularly Imprinted Polymers for Thermal Biosensors

Ana I. Furtado, Sérgio F. Sousa, Bart van Grinsven, Joseph W. Lowdon et autres

Abstract Supercritical carbon dioxide (scCO2) offers a sustainable medium for molecularly imprinted polymer (MIP) synthesis, yet rational monomer selection under supercritical conditions remains largely unexplored. Here, molecular dynamics (MD) simulations were used as a pre–polymerization screening tool to investigate template–monomer interactions for …

Sustainable development of dual–templating molecularly imprinted polymers for biopurification

Ana I. Furtado, Diogo Lobato, Vasco D. B. Bonifácio, Raquel Viveiros et autres

The demand for bio–based products is increasing, but the development of efficient purification processes is lagging. However, typically these processes are expensive, non–specific and/or lack of efficiency. Molecularly imprinted polymers (MIPs) are synthetic affinity materials able to mimic the molecular recognition ability …
