Chemically engineered AuNP/PB-GFP interface for H2O2 sensing. A) Schematic illustrating the interfacing of AuNP-Gal with PB-GFP, and phorbol 12-myristate-13-acetate (PMA) stimulated in situ H2O2 generation modulated GFP release from the AuNP/PB-GFP interface. B) Reaction mechanism of PB-GFP with H2O2 catalyzed bioorthogonal PB cleavage.
