FRIDAY, Sept. 28, 2018 (HealthDay News) — A device inspired by the Star Trek famous tricorder device pairs a handheld sensor with a smartphone app to measure the levels of various metabolites associated with multiple diseases in fluid samples from patients, according to a report published in an upcoming issue of Biosensors and Bioelectronics<\/i>.<\/p>\n
Samadhan B. Patil, Ph.D., from the University of Glasgow in the United Kingdom, and colleagues reported the development of a handheld device based on complementary metal oxide semiconductor technology.<\/p>\n
The researchers note that the device includes multiple isolated micro-well reaction zones and integrated optical sensing allowing simultaneous enzyme-based assays of multiple metabolites associated with diseases. The metabolites (choline, xanthine, sarcosine, and cholesterol) are measured in clinically relevant concentration ranges. The device is linked to an Android-based user interface; within two minutes of applying samples to the device, metabolites in serum and urine are quantified. By comparison to accredited tests for cholesterol and glucose, the quantitative performance was validated.<\/p>\n
“We have been able to detect and measure multiple metabolites associated with myocardial infarction, or heart attack, and prostate cancer simultaneously using this device,” Patil said in a statement. “This device has potential to track progression of the disease in its early phase and is ideally suited for the subsequent prognosis.”<\/p>\n
