Silver Loaded Zeolite Beads: Synthesis, Characterizations and its Antibacterial Study via Spot Diffusion Technique

Due to wide applications of antibiotics, the multidrug resistance in microorganisms are a serious concern. There is urgent need to develop suitable methods to produce antibacterial materials in large quantity and develop materials which have antibacterial properties. In this regard, we worked to prepare a composite of silver loaded zeolite and studied its applicability as antibacterial material. Zeolite beads loaded with different concentrations of silver was prepared and characterized using various techniques like SEM, FTIR, BET, AFM etc. For studying its antibacterial property, E. coli (gram negative) and S. aureus (Gram positive) microorganisms were used as model system. In antibacterial study, it was observed that silver loaded zeolite has antibacterial property against both E. coli (gram negative) and S. aureus (Gram positive) microorganisms.
