Synthesis and Evaluation of the Influence of pH on the Luminescent Properties of Ag-Doped ZnSe Nanoparticles and Their Antibacterial Ability Toward Biomedical Applications
摘要
Quantum dots, also known as semiconductor nanoparticles, are widely employed in many different industries due to their superior optical qualities, high luminescence intensity, and higher durability over standard dyes. In this study, we have discovered the optimal pH to facilitate the environmentally friendly production of Ag-doped ZnSe nanoparticles (Ag@ZnSe NPs) in an aqueous phase. As a stabilizer, 3-mercaptopropionic acid was employed in the synthesis process. Three steps were taken to complete the reaction in a flask with three necks. To provide adequate water solubility with an appropriate salt concentration and to save expenses, acetate salts were utilized as the agent. Ag-doped ZnSe NPs, resulting in maximum luminescence efficiency at pH 7. The size of the nanoparticles formed was determined by UV-vis absorption spectroscopy and TEM images. In accordance with the X-ray diffraction pattern, the crystal created has a cubic crystal structure. The antimicrobial properties of the Ag@ZnSe NPs against P. aeruginosa were investigated using the diffusion method. The results indicate that Ag@ZnSe NPs have antibacterial properties for biomedical applications.
