Urinary catheter coated with infection prevention material derived from agricultural residue, receiving an award at Thailand Research Expo 2017.

Cutting edge research “Antibacterial coated urinary catheter from agricultural residue” from Ms. Fueangfahkan Chutrakulwong, a PhD student from the Department of Physics, Faculty of Science, King Mongkut’s University of Technology Thonburi (KMUTT), with Assistant Professor Dr. Kheamrutai Thamaphat as the research advisor.  

Miss Fueangfahkan Chutrakulwong, the research owner mentions that “Presently, the nosocomial infection in hospitals is a critical concern in the public health system of every country. Each year, there is a significant number of patients being infected during their admission to the hospital care increasing the fatality and disability rate. From these radical concerns, the nosocomial infection group within hospitals have been working with the Department of Disease Control, Ministry of Public Health, to investigation the impact of the infection. Surprisingly, the urinary tract infection was ranked first in terms of nosocomial infection and is at a 30 percent infection rate from all hospitals in Thailand. The main causes for the urinary tract infection is from leaving the urinary catheter in the patient for too long in patients with urinary excretion problems. The reason of the infection from leaving the urinary catheter can be categorized to two factors. First is the external factor where the bacteria enters before inserting the catheter which has yet to be disinfected. The second is the internal factor which usually is from leaving the urine bag which has been left and returned through back flow. Therefore, if there is a urinary catheter with the properties to prevent bacterial infection on the urinary tract, prevent clogging in the catheter, and preventing the clogging of biofilm, this will significantly reduce the fatality rate and the expense of the patent and familial relatives. From our study, we have identified that silver nanoparticles have the properties to inhibit and kill bacteria up to 650 types, holds good compatibility with living organism tissues, and can be applied to the medical field in various ways.  Therefore, green chemistry has been a major sector for research and developing new technology and innovation such as the process to synthesis the material or chemical, by reducing and avoiding the harmful chemicals which affects the user during the manufacturing process. This also looks at the protection and preventing the harmful chemicals to be released to the environment and the related worker for the manufacturing process. Therefore, the inventors foresee the importance of developing a urinary catheter which is affordable and holds the ability to prevent bacterial infection with applied green technology as an innovation to coat the urinary catheter to protect against urinary tract infection. These silver nanoparticles coated urinary catheter, from agricultural residue, is affordable and adds value to these agricultural waste making a product for commercialization purposes showing the quality of how Thai researchers are going to be more beneficial for the society and Thailand’s nation”.

This research has received the outstanding award with the project proposal on the invention and innovation in the field of higher education 2017 and received an outstanding award in the contest for invention and innovation in higher education 2017, in the Health, Wellness, and BioMed group. Also receiving the cash prize with the trophy and certificate for participating in the “Thailand Research Expo 2017”, in the theme of “Research for developing the country towards rich and sustainability” organized by the National Research Council of Thailand (NRCT) with the national’s network of research.
