Liquid phase preparation and characterization of MgO nanoparticles and their butchery activities against dental bacterial pathogens and human cervical cancer cell line.

A novel method for synthesizing nanomaterials involves microbial or phytochemical nano-factories, which offer an eco-friendly, cost-effective, and reliable approach to producing clean and reproducible products. In this study, magnesium oxide nanoparticles (MgO NPs) were synthesized using Avicennia marina, a marine plant, as both a nucleation and stabilizing agent. The MgO NPs were characterized for crystallinity, cut-off wavelength, morphology, thermal stability, and surface properties using XRD, EDX, BET, UV-Visible spectroscopy, DLS, zeta potential analysis, SEM, TEM, TGA/DTA, and PL spectroscopy.

Antibiofilm and antimicrobial efficacy evaluation of polypyrrole nanotubes embedded in aminated gum acacia based nanocomposite.

The sustainable development of natural polysaccharide-based hybrid composites is highly important for the effective replacement of metal nanoparticles in diverse applications. Here, polypyrrole nanotubes (PPyNTs) were embedded on the surface of aminated gum acacia (AGA) to produce ecofriendly nanocomposites for biomedical applications. The morphology of a PPyNT-enhanced AGA (PPyNT@AGA) hybrid nanocomposite was studied by scanning electron microscopy and transmission electron microscopy and their affirmed interactions were characterised by X-ray diffraction, Raman, Fourier transform-infrared and UV-visible spectroscopy.

Size controllable, pH triggered reduction of bovine serum albumin and its adsorption behavior with SnO/SnS quantum dots for biosensing application.

The pH dependent size control of Bovine Serum Albumin (BSA) and its biosensing potential with Tin Oxide and Tin Sulfide Quantum Dots (SnO/SnS QDs) is reported. The role of disulfide bond cleavage in BSA at acidic and circumneutral pH conditions (3 and 7.2) with sodium borohydride as reducing agent, makes changes in its stability, prone to aggregation and microcapsule formation respectively.

Interactive Studies on Synthetic Nanopolymer decorated with Edible Biopolymer and its Selective Electrochemical determination of L-Tyrosine.

Herein, an edible biopolymer amine Modified Gum Acacia (MGA), successfully encumbered with Electron Beam irradiated Polypyrrole Nanospheres (EB-PPy NSs), was investigated for the effective role in L-Tyrosine (Tyr) biosensing application. The morphology of EB-PPy NSs decorated MGA (EB-PPy/MGA) hybrid nanobiocomposite has been studied by Scanning electron microscopy and its affirmed interactions were characterized by X-ray diffraction, Raman, FT-IR spectroscopy, UV-Visible spectroscopy, Thermo Gravimetric Analysis and Vibrating Sample Magnetometer. The hybrid nanobiocomposite manifested diamagnetic behavior with reduced saturation magnetization (M = 1.
