description: Chronic wounds and burns are currently a serious challenge in the world of health.   The wound is particularly susceptible to infection by bacteria, especially by bacteria   such as Pseudomonas aeruginosa and Staphylococcus aureus. The ineffectiveness   of antibiotics in treating wound infections has encouraged scientists to develop   other alternative treatments, such as nanotechnology-based drug preparations in the   form of ointments and gels. Gold nanoparticles have the advantage of being able to   inhibit antibacterial activity because they can penetrate the microbial cell membrane   easily, causing leakage of cell contents and microbial death. The purpose of this   study is to obtain the best chitosan bioreducer volume, optimal synthesis time,   HAuCl4 concentration and the best chitosan bioreducer concentration in   synthesizing gold nanoparticles that are able to inhibit bacterial growth and   characterize chitosan encapsulated gold nanoparticles. The gold nanoparticle   synthesis in this study uses the sonication method with chitosan as a bioreductor.   The results obtained showed that the smallest nanoparticle gold size was 180.1 nm   and the PDI value was 0,433. The optimum conditions for the synthesis of gold   nanoparticles by sonication method are at 60oC, volume of 5 ml of 2% chitosan   bioreductor, concentration of HAuCl4 10 mM and synthesis time of 45 minutes. The   average inhibition of gold nanoparticles against S. aureus bacteria was 7,99 mm,   while against P. aeruginosa bacteria was 7,03 mm.
