Editorial: Emerging trends in biosensors: bridging chemistry and practical applications

These four articles collectively point to a core insight: chemistry is not merely a tool for biosensors, but rather their intrinsic determinant. The performance of each sensor -sensitivity, specificity, response speed, and stability-is ultimately governed by the controllability, reversibility, and efficiency of the underlying chemical reactions. More importantly, these studies all follow a similar structure-activity relationship paradigm: by systematically varying chemical parameters and precise
