Preparation of herbal formulation and it’s application on nanoparticles synthesis and antibacterial activity

Abstract

Copper nanoparticles makes important progress in the area of nanotechnology and nanomedicine due to their good optical, electrical and anti-fungal/bacterial application. It is prepared using some methods such as vacuum vapour deposition, microwave irradiation methods, chemical reduction and laser ablation. The chemical reduction method is simple, inexpensive and gives a liable control of geometrical nanoparticle characteristics like size and shape. 20 millimolar of 80 ml copper sulphate prepared using double distilled water. The plant extract is added with the metal solution and was made into 100 ml solution. The synthesised nanoparticles solution is preliminarily characterized by using UV- vis-spectroscopy, 3ml of the solution is taken in curette and scanned in double beam UV-vis- spectrophotometer from 300 nm to 700 nm wavelength. The agar well diffusion method is used. Different concentration of Cu NPs was tested against Staphylococcus aureus, Streptococcus mutans (gram +), Enterococcus sp and Pseudomonas sp. The result reveals that Moringa Oleifera mediated with copper nanoparticles show effective antibacterial activity. CuNPs ex significantly higher activity with an increase in the zone of inhibition diameter. The plant extract is observed to be dark green, and the copper nanoparticles are seen to be in light greenish in colour. They can be used in toothpaste and oral medicines due to their antibacterial activity. Nanoparticles are expected to be used in future for the effective drug systems and immunity against diseases.

Performance of Ag-doped CuO nanoparticles for photocatalytic activity applications: Synthesis, characterization, and antimicrobial activity

“…In this experiment, an antimicrobial efficiency of Ag doped-CuO NPs at numerous dosages (20,40,60,80, 100, and 120 µg/mL) was screened against some human pathogens such as; Klebsiella pneumoniae (I), Escherichia coli (II), Klebsiella Rhinoscleromatis (III), Salmonella organisms (IV), Staphylococcus aureus (V), Bacillus cereus (VI), Candida glabrata (VII), and Candida albicans (VIII) using agar welldiffusion method [26]. The LB agar medium was equipped and sterilized in an autoclave for 20 min at 121 °C before being poured down into Petri dishes (14 cm).…”

Antioxidant Vitamins (Vit C and E) Protect the Kidney from Glyphosate- Exposed Renal Damage in Experimental Rats - A Molecular Study

“…The word "vitamin E" refers to a collection of fat-soluble chemicals with specific antioxidant properties that Evans and Bishop initially identified in 1922 and which are vital to human health [24]. Vitamin E may be found in foods that contain fat [25], and since it can be stored in the fatty tissues of both humans and animals due to its fat-soluble nature, it is not necessary to take it daily. When fat is subjected to oxidation and during the spread of free radical reactions, vitamin E, a powerful chain-breaking antioxidant, prevents the synthesis of reactive oxygen species molecules.…”
