Abstract:
Bacterial cellulose (BC) is a versatile material with a very high hydrogel properties that can be used for wound dressing. BC increase the rate of healing by providing a moist environment along with absorb exudates. BC have desired properties such as biocompatibility, high porosity, high water absorption capacity, flexibility and also association with other materials and drugs without changes in characteristics. Since BC is inherently lacking antimicrobial activity, here the antibacterial BC is introduced through in-situ synthesis of silver nanoparticles. BC was produced with Acetobacter xylinum in the suitable environment for one month along with solution of silver nitrate. The obtained BC was tested for antibacterial properties against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli bacteria. The remaining solution on the product indicated synthesis of silver nanoparticles as proved by UV-vis spectra. Also silver nanoparticles were in-situ synthesized on BC layer through using silver nitrate. This also confirmed the synthesis of silver nanoparticles in the remaining solution using UV-vis spectra. Further, scanning electron microscopy (SEM) of the formed BC proved formation of nanosilver on the BC layer in synthesis method. Also, vertical wicking test was carried out to show hydrogel properties of the BC layer confirming the good hydrogel properties
