The present study reports an environmentally safe synthesis of CuO NPs employing Echinophora platyloba DC extract. The production of CuO NPs was authenticated using various analytical characterization techniques such as FT-IR, TEM, XRD, SEM-EDX, DLS, zeta potential, and UV-Vis. The DPPH assay was employed to assess the scavenging efficacy of synthesized CuO NPs. The results of the MTT assay exhibited that CuO NPs have efficient anticancer potential on two used cancer cell lines (MCF-7 and Burkitt's lymphoma). Thus, it tempts us to study the synthesized CuO NPs biocompatible aspects by interactions with several biologically significant molecules. The present experimental evidence demonstrates the direct interaction of CuO NPs with DNA, which might be one of the credible highways elevating its anticancer potential. Moreover, we investigated the interaction of CuO NPs with the most important blood proteins (HSA, HHb, and Lys) in simulated physiological conditions using spectroscopic methods. The interaction findings suggest that the native conformation of the above proteins was preserved at the level of secondary structure in spite of complex formations with CuO NPs. The binding constant values revealed the greater binding affinity of CuO NPs with HSA, HHb, and Lys as compared to ct-DNA; the binding affinity was found in the order HSA > HHb > Lys > ct-DNA.

“…This inhibitory zone was comparable to chlorphenicol (0.66 mm). The exact antibacterial mechanism of AgNPs is unknown, but it seems they interact with the sulfhydryl group of proteins and DNA bases to inhibit respiration and replication in bacteria [41][42][43][44]. The antibacterial effect of Bio-AgNPs against S. aureus and E. coli was higher than that of Chem-AgNPs.…”

Nowadays, membranes and filters made of nanofibers are extensively considered in various fields, such as medicine, water purification, etc. Using an environmentally-friendly method, this study fabricated a nanofiber-based on PVA, bentonite, and silver nanoparticles (AgNPs) with good mechanical strength. Due to conventional AgNPs synthesis methods' toxicity, AgNPs were synthesized by Fusarium sporotrichioides. The MGYP culture medium and the AgNO3 12 M were optimal for Bio-AgNPs synthesis. Bio-AgNPs particle size and zeta potentials were 58 nm and -16.8 mV, respectively. The growth inhibition zone of Bio-AgNPs in E. coli and S. aureus was 0.53 and 0.80 mm, respectively and comparable with chloramphenicol. Then, the optimized Bio-AgNPs and a sample with chemical synthesis AgNPs were used to prepare the PVA/nano-Bentonite/nano-Ag (PVA/NB/AgNPs) nanofiber. The presence of silver in the nanofibers was confirmed through EDX and XRD methods. The diameter of nanofibers was 230 nm. The antibacterial activity of PVA/NB/Bio-AgNPs nanofibers was significantly better against both gram-positive and gram-negative bacteria compared to PVA/NB/Chem-AgNPs nanofibers. The produced membrane is suitable for water treatment, food packaging, and wound dressing because of its good thermal, mechanical, and antibacterial properties.

“…91 A mai napig rendszeres probléma, hogy a tanulmányok primer részecskeméret meghatározásra használják a DLS eredményeket, amelyet a korrelációs függvények analíziséből származó méreteloszlási diagramok (PSD -particle size distribution) valamelyikének önkényes bemutatásával igazolják. 92,93 Habár egy nagyfokú stabilitást és monodiszperzitást mutató minta esetében ezek a PSD-k valóban hasonló eredményeket mutatnak a primer részecskék méretével, az esetek jelentős részében ezek a tulajdonságok eltérnek az ideálistól. Erősen polidiszperz, illetve nagyfokú aggregáltságot mutató minták esetén ezek a diagramok pontatlanok lehetnek, vagy akár teljesen fals eredményeket mutathatnak.…”
