Antibacterial Properties of Dandelion Extract-Based PVA/CTS/DAN/CuNP Composite Gel

Processes, Journal Year: 2024, Volume and Issue: 12(9), P. 1809 - 1809

Published: Aug. 26, 2024

Dandelion extract is a reducing agent, and CuSO4∙5H2O was used as carrier to create copper nanoparticles (CuNPs). A novel polyvinyl alcohol–chitosan–dandelion–CuNP (PVA/CTS/DAN/CuNP) gel acquired by cross-linking Polyvinyl alcohol (PVA) chitosan (CTS) solution. Its structure analyzed using Fourier transform infrared spectroscopy, Scanning electron microscopy, X-ray diffraction. The PVA/CTS/DAN/CuNP gels manifested good stability, recycling ability, swelling properties, biocompatibility. Using the agar diffusion method, diameters of inhibition zone composite against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa could be over 21 mm. In conclusion, had antibacterial performance, which has high potential for application in microbial contamination treatment environmental protection.

In Situ Crosslinked Biodegradable Hydrogels Based on Poly(Ethylene Glycol) and Poly(ε-Lysine) for Medical Application

Molecules, Journal Year: 2024, Volume and Issue: 29(22), P. 5435 - 5435

Published: Nov. 18, 2024

Hydrogels have emerged as promising biomaterials due to their excellent performance; however, biocompatibility, biodegradability, and absorbability still require improvement support a broader range of medical applications. This paper presents new biofunctionalized hydrogel based on in situ crosslinking between maleimide-terminated four-arm-poly(ethylene glycol) (4-arm-PEG-Mal) poly(ε-lysine) (ε-PL). The PEG/ε-PL hydrogels, named LG-n, were rapidly formed via amine/maleimide reaction by mixing 4-arm-PEG-Mal ε-PL under physiological conditions. corresponding dry gels (DLG-n) obtained through freeze-drying technique.
