Label-free fluorescent ionic liquid-functionalized silicon nanoparticles with tunable amphiphilicity for highly sensitive and selective detection of Hg2+ were synthesized.
In this work, a simple, selective, and sensitive probe for hemoglobin based on the quenched fluorescence of silicon nanoparticles (SiNPs) was fabricated. The SiNPs were synthesized by a simple hydrothermal treatment from N‐[3‐(trimethoxysilyl)propyl]ethylenediamine and sodium citrate. The as‐prepared SiNPs exhibited good water‐solubility and high fluorescence with the quantum yield of 70%. The fluorescence of the SiNPs could be remarkably quenched by hemoglobin. A wide linear range was obtained from 50 nM to 4000 nM with a LOD of 40 nM. The quenching mechanism was investigated by UV‐Vis absorption spectrometry and time‐resolved fluorescence spectrometry.
Li-B alloy presents higher voltage and better power performances than those of conventional Li-Al and Li-Si anodes for thermal batteries. Herein, electrochemical characteristics of Li-B alloy in the LiCl-LiBr-KBr electrolyte,...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
