Biosensor for diagnosing diseases

movil_diapScientifics developed in the 70s the method for diagnosis of diseases used today. This system is blood and urine tests based to detect and diagnose diseases, requiring laboratories and personnel. This protocol is economically and time costly, requiring at least two hours to perform the necessary tests.

A device developed by researchers at the University of Leeds could reduce the time of diagnosis to a few minutes, and allow testing in the doctor’s own practice, that is allowing a faster diagnosis, less expensive and more convenient for the patient. The system uses antibodies to detect corporal molecules used to identify physical diseases, called biomarkers, in blood and urine.

The project ELISHA developed the diagnostic device, which has the size of a credit card payment machine, but they expect to reduce its dimensions to a mobile phone size.

The system has a similar function to existing diabetics glucose biosensors, that report with a simple yes or no if exists a wide range of diseases such as prostate cancer or ovarian cancer, multiple sclerosis or heart diseases.

The authors suggest other possible uses of the device such as the detection of herbicides or pesticides in the water or the presence of antibiotics in milk.

In three years is expected to start its marketing. Maybe then the trauma experienced by patients in the series “House” until the famous doctor gets final diagnosis will go even further from the truth than nowadays.
