New Hand-Held Breathalyser May Help Detect Diabetes And Cancer
A handheld device that detects signs of diabetes and cancer in a person's BREATH in exhaled air. It analyses volatile organic compounds (VOCs) emanating from human exhaled breath that can provide deep insight into the status of various biochemical processes in the human body. VOCs can serve as potential biomarkers of physiological and pathophysiological conditions related to several diseases.
The research has been published in the journal Advanced Material.
A prototype of the device, which will look similar to the technology cops use to detect alcohol in breath of drunk drivers, is being created.
This highly-sensitive sensor has been created from a material called a 'nanoparticle scaffold' which is made of tiny pieces of metal and semiconductors and thousands of times smaller than a human hair. This media architecture consists of a stochastically ordered distribution of plasmonic nanocrystals in a fractal scaffold of high‐index semiconductors. The authors noted that the self‐assembly mechanism of this fractal architecture allows fabrication of micrometer‐thick media over surfaces of several square centimeters in a few seconds.
