College of Science, University of Karbala discussed a master dissertation on the preparation of hybrid nanoparticles of titanium dioxide doped with silver using hydrothermal technology by the postgraduate student, Ms. Mona Hassan Hamza.

The dissertation highlighted the nanostructures of pure titanium dioxide doped with silver at different ratios using hydrothermal technology, as well as studying the factors affecting the dimensions of these nanostructures and their antibacterial effectiveness against Gram-positive and Gram-negative bacteria.

The dissertation concluded that adding different ratios of silver contributed to reduce particle size and enhancing their biological activity, the silver-doped samples demonstrated significant antibacterial activity, as well as demonstrating that the shape and size of the particles are directly affected by manufacturing parameters, which impacts their medical and biological effectiveness.

The dissertation confirmed that these developed nanomaterials could represent a promising alternative in the field of antibacterial action, particularly in sensitive medical applications. 

The dissertation recommended further study of the effect of heat treatment conditions on biological properties and the use of other manufacturing techniques to increase the efficiency of the materials and enhance their effectiveness in future uses.
