AI Article Synopsis

  • * TiO was synthesized using the sol-gel process, and the silver nanoparticles were integrated using ultrasonics, resulting in a particle size of 92.4 nm.
  • * The study found that a TiO-Ag nanosuspension showed strong antifungal activity, particularly at a concentration of 0.5% when exposed to visible light.

Article Abstract

Cocoa pod production has experienced a significant decline due to attacks by the () fungus, which is the main cause of cocoa pod rot. To overcome this problem, Titanium dioxide (TiO) was chosen because of its potential as an antifungal, and its activity can be increased by adding silver nanoparticles (AgNPs). This research aims to determine the antifungal properties of TiO-Ag nanosuspension on the growth of under exposure to UV, Visible and without irradiation. The sol-gel process was used to synthesize TiO, and ultrasonics was used to integrate silver nanoparticles into TiO. Characterization of UV-Vis diffuse reflectance spectroscopy (UV-DRS) shows a change in the energy gap from 3.24 to 2.82 eV. The Fourier confirmed the crystal structure of the TiO-Ag anatase transform infrared spectroscopy (FTIR) spectrum, which showed the stretching vibration peak of the Ti-O and Ag-O bonds (463.88 cm). Particle size analysis (PSA) characterization revealed that the nanoscale of TiO-Ag was 92.4 nm. The disc diffusion method was used to test the antifungal inhibitory of 0.1%, 0.3%, and 0.5% TiO-Ag against . The antifungal activity of the TiO-Ag showed strong resistance under exposure to visible light, and the optimum concentration of TiO-Ag was 0.5%.
