Biosynthesis of Copper Oxide nanoparticles from Drypetes sepiaria Leaf extract and their catalytic activity to dye degradation

Cymbopogon Citratus Functionalized Green Synthesis of CuO-Nanoparticles: Novel Prospects as Antibacterial and Antibiofilm Agents

“…The spectrum of CLE-CuONPs (Figure 4A ii) shows that the appearance of sharp bands at 3572, 3488 and 2926 cm −1 are likely due to stretching of -OH, -NH and CHO groups associated with the skeletons of CLE bio-actives [38]. Changes in the sharp peak at 1628 cm −1 in the CLE-CuONPs spectrum justify the role of -C=O stretch of ester and amide groups in NP formation (Figure 4A i,ii) [39]. Similarly, the formation of a series of sharp peaks between 1152 and 611 cm −1 was described in Supplementary Data (Table S1).…”

Tunable electrochemistry and efficient antibacterial activity of plant-mediated copper oxide nanoparticles synthesized by Annona squamosa seed extract for agricultural utility

“…The peaks at 685, 607 and 484 cm À1 were ascribed to the stretching vibration of the C-OH bond. 27,28 Thus, the FT-IR results suggested the formation of the pm-CuO NPs. Further, in the zeta-potential analysis of pm-CuO NPs, a negative potential of À21.5 mV was displayed (see ESI Fig.…”

Green Approach for Synthesis of Cuo Nanoparticles and their Application in Antimicrobial Activity

“…Deep blue colour of the copper nitrate solution changes to dark brownish colour. Dark brownish colour indicates the formation of CuO nanoparticles [11]. Another study reported the synthesis of CuO nanoparticles by reacting plant extract with CuSO 4 solution.…”

“…Of the available processes, biosynthesis of nanomaterials using green reducing agents and plants has been reported [10]. Biosynthesis process have a lot of advantages in the synthesis of nanoparticles due to cost-effective, eco-friendly and better alternative to physical and chemical methods [11]. Moreover, other chemical methods employ toxic chemicals, additives or capping agents and non-polar solvents in the synthesis procedure and are thus not suitable for their application in clinical and biomedical fields.…”
