Researcher develops Electrical nanobiosensor to detect cancer

TEHRAN, Oct. 15 (MNA) – A University of Tehran researcher has developed electrical nanobiosensor capable of detecting cancer.

Mohammad Abdolahad, the developer, told Mehr News that the biosensor would prove effective in diagnosing metastatic cancer.

“The nanobiosensor (CNT-ECIS) incorporates nanostructures as carbon nanotubes and silicon nanowire with applications in monitoring dynamics of cancerous tumors,” he added.

“Use of nanostructures improves sensing properties and precision and quality of signals received from cells,” the researcher said. “Carbon nanotubes detect cells’ dielectric properties induced by disease or medicine side-effects due to their excellent conductivity; they detect changes with precision up to single cell levels, thus making it possible to diagnose cancer in the cells through parameters such as electrical resonance,” he detailed about the biosensor.

Abdolahad also pointed to advantages of the nanobiosensor. “The sensor monitors cells’ vital signs through electrical signals, and detects the effect of medications administered to fight cancer on cell metabolism through these signals,” he said.

“A projected application of the biosensor is to help study the effect of different stimulants and medications on cell vital signs in terms of cell biochemistry, biology, and pharmacology,” the researcher told Mehr News. “The biosensor has been approved by Taleghani Hospital Medical Nanotechnology Research Center, and have passed tests on lung and intestinal cancer cells,” he added. “The product has been registered in USPO in 2013; it is the first product developed in the country with no foreign model extant,” Abdolahad asserted.
