Aggregation-induced emission (AIE) or aggregation-induced enhancement (AIEE) has endowed gold species with responsive fluorescent properties, favoring their potential applications in sensing, imaging, and therapy. However, it remains an interesting challenge to fabricate fluorophores both AIE AIEE effects. Herein, we presented highly luminescent Au(I) thiolate nanocomplex-based biosensors Zn2+ induced-AIE zeolite imidazolate framework (ZIF-8) induced-AIEE The nonemissive monovalent gold–glutathione complexes (AuI-SGs) were obtained synthesize the core–shell Zn2+/AuI-SG@ZIF-8 composites strong luminescence via coordination-assisted self-assembly strategy. By immobilizing GOx on surface of Zn2+/AuI-SG@ZIF-8, Zn2+/AuI-SG@ZIF-8/GOx exhibited effective responsiveness glucose, showing a "turn-off" detection model. mechanism study revealed that robust glucose sensing was attributed acid-stimulated degradation probe facilitated by H+ generated from oxidase (GOx)-catalyzed oxidation process. To achieve noninvasive intelligent blood detection, Zn2+/AuI-SG@ZIF-8/GOx-loaded microneedle (MN)-patch platform further developed. MN-patch-based had promising performance for on-needle capture situ detection. This demonstrated universal feasible protocol construct development MN-based analytical devices.
