Synthesis of ZnO nanoparticles using leaf extract of Tectona grandis (L.) and their anti-bacterial, anti-arthritic, anti-oxidant and in vitro cytotoxicity activities

Abstract

The novelty of this present work is the investigation of the anti-bacterial, anti-arthritic, anti-oxidant and in vitro cytotoxicity activities of green synthesized Zinc Oxide Nanoparticles (ZnO NPs) using leaf aqueous extract of Tectona grandis (L.).

Eco-friendly approach to control dengue vector Aedes aegypti larvae with their enzyme modulation by Lumnitzera racemosa fabricated zinc oxide nanorods

“…where h and c refers to planks constant (6.626 × 10 −34 J s) and velocity of light (3 × 10 8 m/s) respectively and 'λ' denotes optical wavelength. The synthesized LB-ZnO NP's optical energy band gap was found to be 3.25 eV which is in good agreement with the previous report [50]. This changes in the optical band gap of LB-ZnO NPs concerning the ZnO nanostructure morphology further confirms that nanostructure crystallinity, crystal growth facets, and crystal grain size lead to the effective band gap of nanostructured ZnO smaller than its bulk value of 3.37 eV [51].…”

“…Mahamuni et al [48] and Ishwarya et al [49] reported a similar shift in the position of the absorption peak of ZnO NPs. Figure 1b shows the optical energy bandgap (Eg) of LB-ZnO NPs which was estimated using the following Tauc formula [50]. where h and c refers to planks constant (6.626 × 10 −34 J s) and velocity of light (3 × 10 8 m/s) respectively and 'λ' denotes optical wavelength.…”

A greener approach towards the development of graphene–Ag loaded ZnO nanocomposites for acetone sensing applications

“…The extracts include leaves, owers, fruits, stems, and roots. 6,7 Within the large family of metal oxide nanoparticles, ZnO based nanocomposites are being used in various applications such as electronics, communication, sensors, cosmetics, environmental protection, biology and medicinal industry. [8][9][10][11][12][13][14][15] ZnO is an interesting material from several points of view.…”
