The main challenge for health care is about inventing new techniques for detecting early-stage lung cancer.

Researchers have technologically invented a graphene-based biosensor that can snuffle the indication of suffering from lung cancer from the breath of person that covers the cost-effective system of early diagnosis.

Scientists from Exeter University located in the UK have invented a procedure that can produce extremely complex graphene biosensor with the potential of detecting the molecules of the biomarkers of lung cancer.

The new structure of biosensor can change the current e-nose equipment that is used for recognizing the particular components of a definite mixture of vapor from person’s breath for analyzing the chemical structure for detecting the cause.

In the journal of Nanoscale, the device was described that shows the capability of identifying exact markers of lung cancer at the initial stage.

One of the scientists commented that graphene biosensor will be highly advantageous and less expensive for the providers of health service all over the world.

A postgraduate scientist from Exeter University, Ben Hogan states that “The new biosensors developed by the Ben Hogan show that graphene has significant potential for use as an electrode in e-nose devices”.
Ben Hogan even claims that “For the first time postgraduate researchers have revealed that with suitable patterning graphene can be used as a specific, selective and sensitive detector for biomarkers”. Ben Hogan even stated that “Postgraduate researchers have faith that with the development of the devices, reusable, cost-effective and exact breath test for the detection of early-stage lung cancer can turn into a reality”.
Lung cancer is the destructive and common cancers, slaying about 1.5 Mn people every year, the absence of the clinical symptoms in early stages where patients are not diagnosed till the last stage which can be difficult to treat.

Owing to the irrepressible nature of the abnormal cancer cells in the lungs, it is susceptible to spread in other body parts.

Currently, there are no simple, cost-effective or largely available methods of screening of lung cancer.
With the help of multi-layered graphene, a team of the postgraduate researchers proposes that e-nose devices are combining electronic sensors with the instruments for pattern recognition like the neural network can develop the breath diagnostic techniques.

By using the multi-layered electrodes of graphene, postgraduate researchers team were able to display the superior sensing abilities for most common biomarkers of lung cancer like acetone, isopropanol and ethanol in the range of various concentrations.
