Enhanced peroxidase-like activity of L-glutamic acid-coated Fe3O4 quantum dots for colorimetric detection of L-cysteine in serum and milk
{{output}}
A novel colorimetric sensing platform was developed for rapid detection of L-cysteine (L-Cys) in human serum and milk samples, utilizing L-glutamic acid-coated Fe3O4 quantum dots (Glu-Fe3O4 QDs) with enhanced peroxidase-like activity. The Glu-Fe3O4 QDs were sy... ...
