Abstract (300 words maximum)
We design composite materials containing silver nanoparticles (AgNPs) and cotton fabric (CF). The cellulose in cotton fabric contains -OH groups. These -OH groups are deprotonated by a pretreatment process, and Ag+ ions are allowed to bind. In a consecutive step, the Ag+ ions are reduced to fiber bound AgNPs generating CF@AgNPs. Three different CF@AgNPs composites are created varying the concentration of precursor AgNO3 solution. The composite materials will be characterized by scanning electron microscopy (SEM), Energy-dispersive X-ray, FTIR spectroscopy, and thermogravimetric analysis (TGA). The CF@AgNPs composites are assessed for the detection of toxins and explosives using surface-enhanced Raman Scattering (SERS) technique.
