Molecularly Imprinted Polymers for the Recognition of Tobacco Viruses

Abstract :-
The goal of this research is to elucidate the mechanism of virus recognition in molecularly imprinted polymers (MIPs) using already utilized techniques. The clinical relevance of this study relates to the development of a virus imprinted MIP, which would apply to the identification, classification, and removal of viruses. The separation of viruses and virus-like particles from various media represents an enormous challenge to the fields of medicine, healthcare, and biotechnology.

Since virus MIPs must function in aqueous environments, our approach employs a more flexible non-covalent imprinting method which starts from a readily available polymer and utilizes an aqueous environment for both MIP synthesis and testing. Crosslinked polymers imprinted against Tobacco mosaic virus (TMV) via non-covalent interactions were synthesized using poly (allylamine hydrochloride) (PAA), epichlorohydrin (EPI), and TMV.

The TMV imprinted polymer exhibited an increase affinity to the target virus compared to the control polymer and demonstrated a preferential affinity (imprinting factor of 2.1), based on shape, to the target virus compared to a non-target virus, Tobacco necrosis virus (TNV). In contrast, there was no significant increase in binding of the control polymer to either target or non-target virus. Once it was determined that virus imprinted polymers can be successfully synthesized having preferential binding to a targeted virus, the synthesis procedure was optimized to obtain better binding characteristics to the targeted virus.
