Innovative Sensor Enhances Chiral Molecule Detection for Pharmaceutical Progress

Revolutionizing the study of molecular structures, a cutting-edge sensor developed at the University of Central Florida (UCF) lends unparalleled precision to chiral molecule detection, a key factor in advancing drug discovery and development. UCF’s NanoScience Technology Center’s Debashis Chanda spearheaded the creation of this plasmonic platform, described in Science Advances, setting new standards for sensitivity and specificity in molecular analysis.

Chirality, a property of molecules where pairs are structurally identical yet oppositely oriented like human hands, plays a significant role in biological and pharmaceutical realms. For instance, enantiomers, or the mirror-image pairs, have distinct interactions within an organism. Their precise identification and separation are critical because more than half of modern drugs are chiral, with large proportions existing as mixtures of enantiomers.

Chanda’s platform targets this challenge, capitalizing on the power of superchiral light induced by a symmetric achiral gold pattern combined with an optical cavity. This innovation produces a distinct reflective difference when exposed to chiral molecules, thereby indicating their presence without interference from the sensor itself. The result is a promising development in the accurate quantification of chiral purity, outmatching conventional methods substantially in sensitivity.

Looking beyond the study, the goal is to integrate this technology into practical applications that enhance the efficiency of drug identification and facilitate the creation of new photonic devices. The promise of low-cost, rapid, and precise detection methods looms on the horizon, potentially transforming pharmaceutical research and contributing to the efficacy and safety of future therapies.

The expertise behind the platform is rooted in Chanda’s exemplary career at UCF and his prior research accomplishments in photonics. His intent with this advancement is to bolster research capabilities, pave the way for novel commercial products, and benchmark a new era in molecular analysis.
