Graphite flake with 100 mesh

All the chemicals in this paper were analytical grade acquired from Merck, HiMedia and Sigma-Aldrich and used without further purification. Iron(ii) sulfate heptahydrate (FeSO₄·7H₂O), hydrogen peroxide (H₂O₂, 30% wt), sodium nitrate (NaNO₃, 98%), concentrated sulfuric acid (H₂SO₄, 98% wt), potassium permanganate (KMnO₄), crystal violet dye (C₂₅H₃₀ClN₃) and sodium hydroxide (NaOH) were from Merck, India; iron(iii) chloride hexahydrate (FeCl₃·6H₂O) from HiMedia, India; and Graphite flake with +100 mesh from Sigma-Aldrich, India. The standard strains of Trichophyton mentagrophytes and Candida albicans (fungus) were obtained from Adhya Biosciences Pvt. Ltd., Visakhapatnam. Milli-Q water was used in the experiment. Pocket-sized pH meter acquired from Hanna instruments was used to regulate the pH of the solutions. Hot Air Oven, Kemi was used to dry washed samples. Dolichos lablab L. pods were collected from market near Andhra University, Vishakhapatnam, India.

Graphite flake with +100 mesh was purchased from Sigma Aldrich. Silver nitrate (AgNO₃), hydrogen peroxide (30 wt%), sodium nitrate (98%), sulphuric acid (98 wt%), potassium permanganate (KMnO₄), and hydrochloric acid (HCl) (Merck, India) were used to synthesis graphene oxide (GO). l-Methionine (Himmide, India) used as a reducing and surface functionalization of GO and Ag⁺. All other chemicals used were analytical graded. Solutions were prepared with ultrapure water (Milli-Q) throughout the experiment.
