A new method in differentiation of chiral molecules is reported based on the fluorescence quenching of functionalized CdS quantum dots (CdS-QDs) as nanosensor by differing in the chirality of functionalization species. The chemically functionalized CdS-QDs with strong yellow emission were prepared using chiral L-cysteine (L-Cyst) and D-cysteine (D-Cyst) molecules. Then, the functionalized CdS-Q...

Abstract In this review, we engineer a high-performing nanosensor mechanic based on SPPs, which consists of metal-insulator-metal waveguide coupled with two triangular plates in double-internal-pile ring cavity (DISRC). The feasibility establishing the sensor SPPs is analyzed theoretically, and parameters DISRC are simulated by finite element method. best sensitivity proposed system 2640 nm/RIU...

Fluorescent nanosensor probes have suffered from limited molecular recognition and a dearth of strategies for spatial-temporal operation in cell culture. In this work, we spatially imaged the dynamics of nitric oxide (NO) signaling, important in numerous pathologies and physiological functions, using intracellular near-infrared fluorescent single-walled carbon nanotubes. The observed spatial-te...
