Iron-Doped Polymer Dots with Enhanced Fluorescence and Dual Enzyme Activity for Versatile Bioassays

Analytical Chemistry, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 7, 2024

Nanozymes with multiple functionalities endow biochemical sensing more sensitive and efficient analytical performance by widening the modes. Meanwhile, target-oriented design of multifunctional nanozymes for certain biosensing remains challenging. Herein, a constructive strategy doping iron into polymer dots (PDs) to achieve excellent oxidase-mimicking peroxidase-mimicking activity is proposed. Compared Fe-free PDs prepared under same mild condition, Fe-doped (Fe-PDs) exhibit greatly boosted fluorescence at 500 nm. While applying 3,3′,5,5′-tetramethylbenzidine (TMB) as chromogenic substrate, Fe-PDs can be further quenched oxTMB due inner filter effect (IFE). Inspired this, simple but colorimetric fluorometric dual-mode platform developed monitoring reducing substances ascorbic acid (AA), α-glucosidase (α-Glu), its inhibitors (AGIs). We believe that such enzyme-mimic materials will provoke exploration multimode strong practicality serve versatile tool in sensing.
