Development of disease treatment and preventive measures to avoid any dangerous outbreak of epidemic proportions are important. Modern methods of detection and treatment include tissue culture, nanotechnology, radiation, and laser technology. We report the synthesis of nanocrystalline materials by combustion method with the use of Aloe vera extract powder. Addition of ZnO changes the structural and optical properties of A. vera. The as-prepared nanocrystalline ZnO (ZnO + A. vera) powders were characterized using XRD, TEM, and SEM. Antibacterial and antifungal tests show that ZnO nanoparticles mixed with A. vera are effective in inhibiting bacterial growth.
