Study on the antibacterial activity and interaction with human serum albumin of Tagetes erecta inspired biogenic silver nanoparticles

Selenium nanoparticles: Synthesis, in-vitro cytotoxicity, antioxidant activity and interaction studies with ct-DNA and HSA, HHb and Cyt c serum proteins

“…15 A, the UV–vis absorption of the peptide bond (226 nm) and aromatic amino acids (278 nm) decreased on elevating the concentrations of nano-selenium (hypochromism), which reveals the formation of nano-selenium–HSA complex during their conjugation. As can be seen, the position of signals at 226 and 278 nm had barely changed, indicating that the conformation of peptide backbone of protein (α-helix content) and microenvironments of amino acid residues didn’t change significantly during the nano-selenium– HSA interaction which is supported by the previously reported works, Maji et al [ 54 , 55 ]. In other words, the native secondary structure of HSA did not change significantly despite complex formations with nano-selenium.…”

Sunlight Photocatalytic Performance of ZnO Nanoparticles Synthesized by Green Chemistry Using Different Botanical Extracts and Zinc Acetate as a Precursor

“…Researchers have also studied the impact of ZnO NPs obtained with Azadirachta indica on antibacterial and antimicrobial properties; they have found that Gram-positive and Gram-negative bacterial growth decreased when the concentration of ZnO NPs increased [ 13 , 14 ]. Additionally, leaf extracts of Tagetes erecta , Chrysanthemum morifolium , and Lentinula edodes have been used for the synthesis of silver nanoparticles for use in antibacterial activity, whose results have been favorable [ 15 , 16 , 17 , 18 , 19 ].…”

Optimization of Flavonoid Extraction from Xanthoceras sorbifolia Bunge Flowers, and the Antioxidant and Antibacterial Capacity of the Extract

“…Bacteria in the logarithmic growth phase was uniformly diluted with sterilized saline to a concentration of 10 6 CFU/mL until it was ready for use, following McMillan’s turbidimetric method [ 32 ]. The Oxford cups were placed on MH agar medium evenly coated with diluted bacterial suspension, and then 100 μL of TF extract samples with different concentrations were injected into the cups [ 33 ]. After 24 h incubation in 37 °C constant-temperature incubator, the diameters of the inhibition zones on the medium were measured with a vernier caliper for analysis [ 34 ].…”
