Plasmonic biosensor platforms for next-generation personalized medical diagnostics.

The increasing healthcare burden demands precise diagnostics for early detection and longitudinal disease monitoring. Although conventional assays such as ELISA and PCR offer precision, they require intensive sample preparation, bulkier instrumentation and prolonged assay times. This review examines plasmonic biosensor...

Smart pH-Sensing Chitosan-Carbon Quantum Dot Hydrogel and Microneedle for Wound Diagnostic Application

Inspired by the wound healing challenges, we reported a chitosan(CS)-derived hydrogel integrated with carbon quantum dots (CQDs) focusing on a biochemical−mechanical regulation synergistic strategy. The modification of CS’s hydrogel matrix by optimized CQD concentration brings a platform with balanced swelling proper...
