Au/GQD hybrid interfaces: signal-transduction principles and evidence for metal-ion sensing
Year: 2026
Type: review
Abstract: . Their comparison reveals heterogeneous recognition mechanisms and incomplete analytical benchmarking rather than a universally validated recognition pathway. A general hybrid advantage remains unestablished without matched component and alternative-material controls. Adjacent Au/GQD assays provide design hypotheses whose transfer requires target-specific binding and interference validation. Persistent limitations include unresolved signal origins, concentration-dependent matrix effects, inconsistent detection-limit reporting, and poorly standardized interface characterization. The resulting synthesis provides a structured basis for interpreting Au/GQD responses and identifying evidence needed to connect interfacial changes with reliable metal-ion detection.
