Resumo
PVGA, silver nitrate (
AgNO3) and alginate (Alg) were cross-linked by using γ-ray
radiation to obtain Alg/PVGA/AgNPs as a potential biomaterial. The hydrogel
composition was characterized by several analytics methods, and the morphology
was evaluated by scanning electron microscopy. The swelling behavior was tested
in different mediums. The stability of AgNPs was followed by UV–Vis at 400 nm
for 1 month. The hydrogel soil biodegradation was analyzed by visual observation,
weight loss, Fourier transform infrared spectroscopy and thermogravimetric analysis
for 120 days. A simple biodegradation mechanism has been proposed based on
results. Additionally, cytotoxicity assays were carried out using NCTC 929 cells to
observe cell viability.
