Abstract EN
Natural carbohydrate polymer β-d-glucan extracted from Tricholoma crassum (Berk.) Sacc.
predominantly linked by β-glycosidic bonds have been used to synthesize gold nanoparticles (Au NPs).
As glucan is water soluble, the Au NPs are prepared in water medium, a green solvent.
The morphology and characterization of the synthesized Au NPs have been confirmed by various techniques, like TEM, EDX, XRD, UV–Vis and FT-IR spectroscopic studies.
The obtained Au NPs exhibits chemosensing property against Methyl Parathion, a group of highly toxic organophosphorous pesticide, extensively used as an agricultural chemical.
Degradation of parathion using Au NPs lead to water-soluble products thereby reducing the toxicity of Methyl Parathion by disrupting the thiophosphate-ester linkage.
The synthesized Au NPs also act as a good fluorescence quencher of Rhodamine B, a common fluorophore and carcinogenic compound, obeying Stern-Volmer equations.
The β-d-glucan capped Au NPs are safe having possible medicinal usage.
