Red Emission B, N, S- co -Doped Carbon Dots for Colorimetric and Fluorescent Dual Mode Detection of Fe 3+ Ions in Complex Biological Fluids and Living Cells
Lanzhou University · University of Science and Technology of China
Abstract
Colorimetric and fluorescent dual mode detection methods have gained much attention in recent years; however, it is still desirable to develop new colorimetric and fluorescent dual mode nanosensors with more simple preparation procedures, low cost, and excellent biocompatibility. Herein, a colorimetric and fluorescent nanosensor based on B, N, S-co-doped carbon dots (BNS-CDs) was synthesized by one-step hydrothermal treatment of 2,5-diaminobenzenesulfonic acid and 4-aminophenylboronic acid hydrochloride. Using this nanosensor, a highly sensitive assay of Fe3+ in the range of 0.3–546 μM with a detection limit of 90 nM was provided by quenching the red emission fluorescence. It is more attractive that Fe3+ can…
