Shiraz researchers design sensors for diagnosis of urinary infections

Shiraz, Jan 4, IRNA - Shiraz University researchers succeeded in designing and producing a sensor for diagnosing urinary infections by using nanotechnology.

'A sum of 16 nanoparticles of gold and silver were used in the design of this sensor, and the interaction of vapors from bacteria in the urine sample with nanoparticles caused a change in the color in the sensor so that the nanoparticles of gold changes from red to violet and silver nanoparticles from yellow to brown,' supervisor of Shiraz university research team said.

Bahram Hemmatinejad added that since the vapors of each bacterium differs from other bacteria, the change in the color of the nanoparticles will determine the type of bacteria and the intensity of the color change and the concentration of the infection.

'The current method for diagnosis of urinary infection is a culture of urine specimens, which its results are determined in 48 hours, but with the help of this sensor, this time is reduced to half an hour,' the chemistry professor at Shiraz University continued.
