Novel fungicide potentiators from plant-based metal nanocomposites
This innovative solution leverages plant-based metal nanocomposites to enhance fungicidal effectiveness, addressing microbial resistance. By using unique metallic nanoparticles in biocompatible hosts, it offers superior microbial inhibition compared to traditional fungicides.
Overview
This research introduces a novel approach to enhancing fungicidal effectiveness through plant-based metal nanocomposites. By integrating unique-shaped metallic nanoparticles with biocompatible plant extracts, this solution addresses microbial resistance to classical fungicides. These nanocomposites, including 'Ag nanoworms' and other UNT-developed 'nanocreatures', have shown to inhibit microbial growth more effectively than current state-of-the-art solutions, such as sulfa drugs and conventional spherical AgNPs.
Technical specifications
The core of this innovation lies in its unique nanostructures, such as 'Ag nanoworms', 'Au nanomosaics', and 'Cu/Cu2O/CuO NPs'. These are combined with plant extracts rich in biomolecules to enhance the fungicidal action of metal nanoparticles. The nanocomposites release metal ions and reactive oxygen species (ROS) to combat fungal growth. Future development includes combining these nanocomposites with standard fungicides and fungicidal antibiotics to assess their effectiveness against fungi like Candida albicans and Fusarium oxysporum. Analytical methods such as UV-Vis, SEM/TEM, and XRD will be used to evaluate their properties.
Technology readiness level
Currently, at Technology Readiness Level 4, this solution has undergone initial validation in laboratory settings, with ongoing efforts to assess its effectiveness in combination with existing fungicides. The focus remains on optimizing metal nanoparticle composition and plant extract variability to maximize antifungal performance.
