Insight into the morphology, pore structure and sorption properties of 4-hydroxy-3-nitrophenylacetic acid imprinted poly(acrylic acid-co-ethylene glycol dimethacrylate) sorbent

In this paper the exploration of specific imprinted sorbent for 4-hydroxy-3-nitrophenylacetic acid (NHPA), an indicator of 3-nitrotyrosine, a biomarker of pathophysiological states, was described. The optimization of synthetic protocol, supported by theoretical studies, allowed to select NHPA imprin...
