| 摘要 | Chitosan nanoparticles were prepared from chitosan with different molecular weight by spray drying method. The morphology of chitosan nanoparticles were characterized by SEM and size distribution and zeta potential values were determined. Effect of chitosan solution concentrations, molecular weight of chitosan (MMW, HMW and VHMW) and size of spray dryer nozzles on average size, size distribution and zeta potential values of chitosan nanoparticles were investigated. Moreover, the effect chitosan nanoparticles and chitosan nanoparticles/amoxicillin complex on Staphylococcus aureus was also tested. The results showed that the average size of chitosan nanoparticles were in the range of 95.5 to 395 nm and zeta potential values of 39.3 to 45.7 mV depended on concentration and molecular weight of chitosan. The lower concentration and molecular weight of chitosan were used, the smaller size of chitosan nanoparticles and the higher zeta potential values were obtained. The testing for antibacterial activity against S. aureus indicated that chitosan nanoparticles strongly inhibited the growth of bacteria with the minimum inhibitory concentration (MIC) of 20µg/mL, which were lower than that of chitosan solution and amoxicillin. The antibacterial capacity of chitosan nanoparticles also depended on size, zeta potential values and molecular weight of chitosan. Complex of chitosan nanoparticles/amoxicillin could improve antibacterial activity of amoxicillin. |
