摘要
The invention relates to an anti-microbial fabric impregnated with a conjugate of silver nano particles and Aloe vera (AgNP+Aloe) colloidal solution having anti-microbial property and size of 15-20nm made by synthesizing 2.5 mL of 30% ammonia solution was added to 5 mL of 10-2 M AgNO3 solution followed by addition of 5 Ml of the Aloe vera extract and a method of producing antimicrobial silver nano-particle and Aloe vera conjugated multi-purpose nano-fabric. The said method comprises steps of: a) preparation of Aloe vera gel extract and preparing required dilution with pure water; b) addition of silver nitrate stock to gel extract of step (a) for synthesis of silver nano particles (SNP); c) visual observation of color change to confirm completion of reaction in step (b); d) selecting desired shape of spherical monodispersed colloidal SNP-aloe having more active facets (electron dense facets) and strongest biocidal action and size of silver nanoparticles ranges from 20 – 40 nm. e) making visual, spectrophotometric & XRD characterization of synthesized SNP- aloe for synthesis of silver nanoparticles confirmed by its yellow colour formation; f) confirming the formation of silver nanoparticles by UV-Vis spectrophotometric characterization of SNP- aloe; g) coating SNP- aloe on desired fabric such as fabrics coated are cotton (a plant derived fabric), silk (an animal fabric) and polyester (a synthetic fabric).
