Comparison of the size of a microchip and a 25-cent coin.
We know that dogs and cats have a highly sensitive sense of smell, so after training, they can help find out what chemicals the body emits when it is sick. And in some cases, researchers have begun training domestic pets to detect cancer or predict seizures.
So, can we make a slight change to this odor and "save" it into a chip to create a disease detector similar to Breath Alcohol Meter? According to CNN (CNN According to reports, in fact, our vision has become a reality. This is a kind of sensor called "digital nose" (digital nose) whose core component is the microchip spectrometer technology invented by Prof. Andrew Kyle.
Originally developed by the research laboratory of the University of Cambridge in the United Kingdom, this sensor has now become a commercial product of Owlstone. Professor Kell said that this sensor has been put into use by some oil industry giants such as BP and Shell, as well as food industry giants Coca-Cola and Nestlé.
The sensor is about the same size as the US dollar dime (about 1.8 cm in diameter). It works by creating a spectrum of chemicals in the air and then identifying the specific structure of each chemical. If the sensor has been set and calibrated to a specific level, it will sound an alarm.
Professor Kyle said: "What's surprising is that there are indeed some compounds in the breath of human beings that can indicate the signs of illness. A series of studies have shown this. In addition, a large number of studies have shown that we can detect cancer. , tuberculosis and asthma."
Ostone Technologies is still working hard to shrink the sensor so that it can be brought to the medical market. Oston hopes to develop the sensor as a diagnostic tool within a few years.
