Fabrication and Characterization of Carbon Quantum Dots from Waste Fruit Extract and Study their Antibacterial Activity

CQDs have emerged as encouraging materials for numerous uses due to their exceptional optical and electronic
properties. In this study, we explore an eco-friendly approach to fabricate CQDs using waste fruit extract as a
precursor. The fabrication process involves simple and cost-effective steps, making it appropriate for scale up.
The obtained CQDs are analysed utilizing spectroscopic and microscopic techniques to know the structural and
optical properties. Besides, the antibacterial activities of CQDs were screened against aquatic Gram-negative
(Klebsiella pneumoniae and Proteus vulgaris) microbial organisms. This research highlights the innovative use
of agricultural waste in nanomaterial synthesis, contributing to sustainable and green chemistry practices.
