Rourkela, May 23
Researchers at the National Institute of Technology (NIT) Rourkela have designd a novel semiconductor device-based biosensor that can identify breast cancer cells without the need for complicated or expensive laboratory procedures.
The device ‘TFET’ (Tunnel Field Effect Transistor) is based on TCAD (Technology Computer-Aided Design) simulation results, that can effectively detect breast cancer cells.
FETs are commonly used in electronics, but here they have been adapted to function as a sensitive detector of biological materials.
Unlike many traditional tests, this biosensor does not need any added chemicals or labels to work.
It uses the physical properties of cancer cells to detect them. Cancerous breast tissues, which hold more water and are denser than healthy tissues, interact differently with microwave radiation. These differences, known as dielectric properties, make it possible to distinguish between healthy and cancerous cells.
The findings of the research published in the Microsystem Technologies journal, showed that the sensor is sensitive in detecting T47D cancer cells due to their high density and permittivity.
It is also highly effective at distinguishing cancerous cells from healthy breast cells, offering improved sensitivity compared to existing technologies.
