An efficient and low-cost surface-enhanced fluorescence substrate for trace detection of melamine in milk samples

One-step assembly of TA-FeIII supramolecular shell on AgNPs surface for regulating fluorescence intensity of quantum dots

“…11) Various effective metal-enhanced fluorescence substrates have been prepared, such as nano-island membranes, nanoparticles, etc. 7,12,13) Semiconductor quantum dots (QD) have attracted great interest due to their excellent optical properties and potential biological value. 14,15) The signal intensity of fluorescent probes is an important indicator in the detection process, so it is necessary to regulate the fluorescence intensity of quantum dot probes in the tested object.…”
