Silver is widely utilized as antimicrobial agent and wound dressing, where its shape, size, surface area, and surface charge play an important role. The aim of present study was to evaluate the impact of biofield treatment on physicochemical and atomic properties of silver powder. The silver powder was divided into two groups, coded as control and treatment. The treatment group received Mr. Trivedis biofield treatment. Subsequently, control and treated samples were characterized using particle size analyzer, X-ray diffraction (XRD) and surface area analyser. Particle size data exhibited that particle sizes d10, d50, d90, and d99 (Size, below which 10, 50, 90, and 99% particle are present, respectively) of treated silver powder were substantially reduced up to 95.8, 89.9, 83.2, and 79.0% on day 84 as compared to control. XRD results showed that lattice parameter, unit cell volume, and atomic weight were reduced, whereas density and nuclear charge per unit volume were found to be increased as compared to control. In addition, the crystallite size was significantly reduced up to 70% after biofield treatment on day 105 as compared to control. Furthermore, the surface area of treated silver powder was substantially enhanced by 49.41% on day 68 as compared to control. These findings suggest that biofield treatment has significantly altered the atomic and physicochemical properties which could make silver more useful in antimicrobial applications.
Overall, biofield treatment has substantially altered the atomic and physicochemical properties of silver powder. Particle size data revealed that d10, d50, d90, and d99 of treated silver powder were significantly reduced up to 95.8, 89.9, 83.2, and 79.0% on day 84 as compared to control. XRD results showed that unit cell volume and atomic weight was decreased up to 0.75%, whereas density and nuclear charge per unit volume and density decreased up to 0.75% as compared to control silver on day 203. Also, the increase in nuclear charge per unit volume indicates that ionic strength of silver (Ag+) probably enhanced, which may improve its antimicrobial activity. In addition, crystalline size was reduced up to 70% in treated silver as compared to control on day 105. Moreover, the decrease in particle size, increases the surface area up to 49.41 % in treated silver powder as compared to control on day 68. Thus, reduction in particle size, crystallite size and increase in surface area may increase the dissolution rate and thus bioavailability, which further attributes to antimicrobial efficacy of treated silver as compare to control.
