“…van der Waals, electrostatic and magnetic forces, etc. Previously, similar results of biogenic CuO-NPs were reported by several studies (Ida et al, 2010;Cheng and Walker, 2010;Chandra et al, 2014;Sagadevan and Koteeswari, 2015;Kimber et al, 2020;Singh et al, 2019) as observed in TEM. John et al (2021) reported the TEM micrographs of CuO-NPs from marine bacteria and reported the synthesis of monodispersed, spherical/ovoidal NPs of 10 nm-70 nm size with ~40 nm average size.…”

Copper oxide nanoparticles (CuO-NPs) have piqued the interest of agricultural researchers due to their potential application as fungicides, insecticides, and fertilizers. The Serratia sp. ZTB29 strain, which has the NCBI accession number MK773873, was a novel isolate used in this investigation that produced CuO-NPs. This strain can survive concentrations of copper as high as 22.5 mM and can also remove copper by synthesizing pure CuO-NPs. UV-VIS spectroscopy, DLS, Zeta potential, FTIR, TEM, and XRD techniques were used to investigate the pure form of CuO-NPs. The synthesized CuO-NPs were crystalline in nature (average size of 22 nm) with a monoclinic phase according to the XRD pattern. CuO-NPs were found to be polydisperse, spherical, and agglomeration-free. According to TEM and DLS inspection, they ranged in size from 20 to 40 nm, with a typical particle size of 28 nm. CuO-NPs were extremely stable, as demonstrated by their zeta potential of −15.4 mV. The ester (C=O), carboxyl (C=O), amine (NH), thiol (S-H), hydroxyl (OH), alkyne (C-H), and aromatic amine (C-N) groups from bacterial secretion were primarily responsible for reduction and stabilization of CuO-NPs revealed in an FTIR analysis. CuO-NPs at concentrations of 50 μg mL−1 and 200 μg mL−1 displayed antibacterial and antifungal activity against the plant pathogenic bacteria Xanthomonas sp. and pathogenic fungus Alternaria sp., respectively. The results of this investigation support the claims that CuO-NPs can be used as an efficient antimicrobial agent and nano-fertilizer, since, compared to the control and higher concentrations of CuO-NPs (100 mg L−1) considerably improved the growth characteristics of maize plants.

Tenofovir alafenamide (TAF) is an antiretroviral (ARV) drug that is used for the management and prevention of human immunodeficiency virus (HIV). The clinical availability of ARV delivery systems that provide long-lasting protection against HIV transmission is lacking. There is a dire need to formulate nanocarrier systems that can help in revolutionizing the way to fight against HIV/AIDS. Here, we aimed to synthesize a polymer using chitosan and polyethylene glycol (PEG) by the PEGylation of chitosan at the hydroxyl group. After successful modification and confirmation by FTIR, XRD, and SEM, TAF-loaded PEGylated chitosan nanoparticles were prepared and analyzed for their particle size, zeta potential, morphology, crystallinity, chemical interactions, entrapment efficacy, drug loading, in vitro drug release, and release kinetic modeling. The fabricated nanoparticles were found to be in a nanosized range (219.6 nm), with ~90% entrapment efficacy, ~14% drug loading, and a spherical uniform distribution. The FTIR analysis confirmed the successful synthesis of PEGylated chitosan and nanoparticles. The in vitro analysis showed ~60% of the drug was released from the PEGylated polymeric reservoir system within 48 h at pH 7.4. The drug release kinetics were depicted by the Korsmeyer–Peppas release model with thermodynamically nonspontaneous drug release. Conclusively, PEGylated chitosan has the potential to deliver TAF from a nanocarrier system, and in the future, cytotoxicity and in vivo studies can be performed to further authenticate the synthesized polymer.

“…In an alkaline media, the resulting hydrazone, a brown complex that can be detected calorimetrically, is generated when pyruvate is combined with 2,4-dinitrophenylhydrazine. AST (GOT/GPT) activity in IU/L = [(Absorbance of the test−Absorbance of control)/(Absorbance of standard−Absorbance of blank)] × concentration of the standard [23]. At pH 10.0, serum alkaline phosphatase (ALP) transforms phenyl phosphate to inorganic phosphate and phenol.…”

The mammary tumor is the world's most frequent ailment, and it is substantially more common in women. There are several forms of treatment and care available in the globe for tumors, the most common of which being chemotherapy, radiation therapy, and surgery with lots of harmful responses. Cancer has been treated since ancient times by herbs with various herbs and metals. synthesized AgNPs-REEE were characterized by Analytical methods such as dynamic light scattering (DLS), Zeta potential, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and Dynamic Light Scattering (DLS).All of the animals in this study had tumors caused by DMBA Apart from the vehicle control group, and they were divided into different groups such as only DMBA(7,12-dimethylbenz[a]anthracene) induced group, treatment group of ethanolic extract of Russelia equisetiformis (REEE) flower and sliver nanoparticles of ethanolic extract of Russelia equisetiformis (REEE) flower and sliver nanoparticles of ethanolic extract (AgNPs -REEE).the dose were decide by acute toxicity study. After compaction treatment time all animal were sacrifices and evaluate parameter like tumor weight, Tumor volume, biochemical parameter, hormonal assay and histopathology of breast tumor. It is observed that the size distribution of AgNPs ranges from 50 to 950 nm.
