Abstract:
A single-atom copper-activated carbon dots@silica nanozyme (CDs@SiO2@Cu) that exhibits both peroxidase-like activity and room-temperature phosphorescence (RTP) at neutral pH was developed, enabling dual-mode glyphosate detection with enhanced selectivity and sensitivity. This work expands RTP CD applications and offers a versatile approach for engineering nanozymes with customizable RTP and catalytic activities.
