The emergence of antibiotic resistance, caused by the improper use antibiotics, is a significant challenge in combating infectious diseases, leading to millions annual fatalities. occurrence antimicrobial side effects catalyzes investigation novel compounds and sources drugs. Consequently, research on biological activity that conducted plants, plant extracts, are produced from components utmost significance. In this study, CtAC/MNPs were obtained reaction activated carbon (AC) fruits Celtis tournefortii (Ct) magnetic nanoparticles (MNPs), CtAC/MNPs-Ag nanocomposite was synthesized reduction silver ions added reaction. nanocomposites analyzed spectroscopically (FTIR, XRD), microscopically (SEM, EDX), optically (DLS), electrochemically (zeta potential) magnetically (VSM). antibacterial activities against S. aureus E. coli investigated microdilution method using minimal inhibitory concentration (MIC) disk diffusion methods. Antioxidant including total phenolic content DPPH cuprac assays, revealed remarkable effect nanocomposite. This study has advantages obtaining short time without requiring energy, most importantly, takes place any toxic substances. addition, according data thought shed light biomedical research.

Influence of the Type of Biocompatible Polymer in the Shell of Magnetite Nanoparticles on Their Interaction with DPPC in Two-Component Langmuir Monolayers

The Journal of Physical Chemistry B, Journal Year: 2024, Volume and Issue: 128(3), P. 781 - 794

Magnetite nanoparticles (MNPs) are attractive nanomaterials for applications in magnetic resonance imaging, targeted drug delivery, and anticancer therapy due to their unique properties such as nontoxicity, wide chemical affinity, intrinsic superparamagnetism. Their functionalization with polymers chitosan or poly(vinyl alcohol) (PVA) can not only improve biocompatibility biodegradability but it also plays an important role interactions biological cells. In this work, the effect of MNPs chitosan, PVA, blend on model cell membranes formed from 1,2-dipalmitoyl-sn-glycerol-3-phosphocholine (DPPC) using a Langmuir technique was studied. The studies performed showed that type biocompatible polymer MNP shell crucial effectiveness its adsorption process into membrane. Modification facilitates significantly more effective than coating them PVA blend. presence all investigated DPPC monolayer at low concentrations does affect thermodynamic state, fluidity, morphology, which is promising terms biocompatibility. On other hand, high concentration (molar fraction above ≈0.05) exerts disruptive membrane results aggregation, leading probably loss superparamagnetic essential nanomedicine.
