A Dual-Emission Probe Based on Silicon Nanoparticles and Rhodamine B for Ratiometric Fluorescence/Colorimetric Dual-Mode Detection of Methyl Parathion
In this study, blue fluorescent silicon nanoparticles (SiNPs) were synthesized via a hydrothermal method by using 3-(aminopropyl)triethoxysilane (APTES) and L-cysteine as precursors. Then SiNPs were combined with rhodamine B (RhB) to form an enzyme-free ratiometric fluorescence probe. Under 383 nm excitation, the SiNPs...
