A novel label-free fluorescence nanosensor was developed for ultrasensitive detection of protamine and heparin based on fluorescence resonance energy transfer (FRET) between NaYF4:Yb,Er upconversion nanoparticles (UCNPs) and gold nanoparticles (AuNPs

High-quality hexagonal upconversion nanocrystals of β-NaYF4:Yb3+,Er3+ were prepared through a one-pot mild solvothermal synthesis. The crystal structure of NaYF4:Yb3+,Er3+ can rapidly transform from cubic (α-) to hexagonal (β-)phase in the presenc

Au nanoparticles (AuNPs) have good absorption properties in the visible region, while upconversion nanoparticles (UCNPs) have an emission at 547 nm upon excitation with a 980 nm laser, which could avoid most interfering signals of biomolecules in ser

We demonstrate that photoluminescent Si-dots exhibit intrinsic peroxidase-like activity, and can catalyze the oxidization of 3,3′,5,5′-tetramethylbenzidine (TMB) by H2O2, and produce a color change. This strategy can be used to detect glucose wit

High quality carbon dots (C-dots) with down- and up-conversion fluorescence have been synthesized through low-temperature carbonization using sweet pepper as the carbon source. The C-dots with a quantum yield (QY) of 19.3% exhibit superior photophysi

Here we report a novel label-free fluorescent sensor for ultrasensitive detection of protamine and heparin based on the high quenching ability of gold nanoparticles to the fluorescence of fluorescein. The fluorescence was significantly quenched when
