Biography

Jayaruk is a graduate of the University of Colombo. He pursued his PhD in Chemistry from The University of Alabama, USA. He has specialized in Materials, Analytical and Physical Chemistry. Currently, he is working as an Assistant Professor at the Department of Applied Sciences, SLIIT. He is the coordinator of the BSc Biotechnology degree programme. He has been awarded the chartered chemist designation by the Institute of Chemistry, Ceylon. He supervises Postgraduate students at the University of Colombo and the University of Kelaniya and supervises undergraduate students at the Institute of Chemistry. He is interested in doing research on using nanomaterials in water purification and as antimicrobial reagents. Further, he is interested in researching on algae and plant materials for their pharmaceutical and cosmeceutical activities. He has specialized in many instruments like Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM), X-Ray Diffractometer (XRD), X-Ray Photoelectron Spectrometer (XPS), Gas chromatograph-Mass spectrometer (GC-MS), Raman Spectrometer, FT-IR spectrometer, UV-Visible Spectrophotometer, Brunauer-Emmett-Teller (BET) surface area analyzer etc. He is interested in practical-based science education and believes in uplifting the research culture among upcoming scientists in the country.

    Bacterial infections have a significant public health impact. Infections are caused by bacteria in animals, plants as well as humans. Pathogenic bacteria can produce toxins, which are chemical poisons that interfere with cell function such as digestion of normal human enzymes, evasion of infection-fighting white blood cells, and immune clearance. Antibiotic prophylaxis is used to prevent bacterial infection. Antibiotic resistance is one of the most serious concerns in world health. Antibacterial nanoparticles are one possible answer to antimicrobial resistance. These nanomaterials not only kill antibiotic-resistant bacteria through various modes of action but, they can also be employed in conjunction with existing clinically relevant antibiotics to help overcome antimicrobial resistance mechanisms. In this study, anodized titanium dioxide (TiO2) nanorods were treated hydrothermally with zinc oxide (ZnO) nanoparticles to give titanium (Ti) antibacterial properties. The antibacterial activity of synthesized samples was investigated by Agar Well Diffusion method at 40 mg/ml concentration, against gram negative Klebsiella pneumoniae. To determine the antibacterial activity, the diameter of the zone of inhibition was measured, and the resulting data were statistically analyzed. Zn/TiO2 nano particles were characterized by using X-ray diffraction (XRD) Analysis.
