Development of cysteine-doped MnO₂ quantum dots for spectrofluorimetric estimation of copper: applications in different matrices.

ABSTRACT: Copper (Cu) plays a role in maintaining healthy nerve cells and the immune system. Osteoporosis is a high-risk factor for Cu deficiency. In the proposed research, unique green, fluorescent cysteine-doped MnO₂ quantum dots (Cys@MnO₂ QDs) were synthesized and assessed for the determination of Cu in different food and hair samples. The developed quantum dots were synthesized with the help of cysteine using a straightforward ultrasonic approach to create 3D fluorescent Cys@MnO₂ QDs. The resulting QDs' morphological and optical characteristics were carefully characterized. By adding Cu ions, the intensity of fluorescence for the produced Cys@MnO₂ QDs was found to be dramatically reduced. Additionally, the applicability of Cys@MnO₂ QDs as a
