Measuring kinetic parameters using quantum plasmonic sensing

The measurement of parameters that describe kinetic processes is important in the study molecular interactions. It enables a deeper understanding physical mechanisms underlying how different biological entities interact with each other, such as viruses cells, vaccines antibodies, or new drugs specific diseases. In this work, we theoretically use quantum sensing techniques for measuring sensor consider plasmonic resonance sensor---a label-free photonic one most widely used research and industry. first type interaction antigen BSA interacting antibody IgG1, which provides large response. second enzyme carbonic anhydrase tumor growth inhibitor benzenesulfonamide, produces small For both types two-mode Fock states, squeezed vacuum displaced states. We find these states offer an enhancement precision when compared to obtained classical light. results may help design more precise quantum-based sensors studying kinetics life sciences.
