Hydrogels Based in Cassava Starch with Antibacterial Activity for Controlled Release of Cysteamine-silver Nanostructured Agents

Conclusion: Hydrogels can be used as controlled-release systems of substance with antibacterial activity (AgNPs, cysa and AgNPs-cysa). Antibacterial effect against Escherichia coli and Staphylococcus aureus was seen to be relatively low at studied concentrations; however, the charge of antimicrobial activity can be controlled as a result of high water absorption capacity. Inhibition percent for hybrid systems (AgNPs-cysa) was seen to be most effective against Escherichia coli and very similar to the observed effect for AgNPs.
