Inkjet printer diagnoses diabetes
A group of chemists has identified a feature of an inkjet printer: it can be used as a chemical laboratory, for example, to detect diabetes with high accuracy.
Do you have diabetes and want to find out your blood sugar? Or want to make sure that you do not have diabetes? Just turn your inkjet printer into a chemistry lab!

Chemists from Tsinghua University took up this study. According to scientists, an inkjet printer is “an amazing achievement of precision engineering,” which can “reach over a million different shades and colors, including the smallest points with high precision. These characteristics of the printer can show millions of different chemical reactions.
Chemist Uyfei Zhang noted that every chemical process that occurs in living organisms is controlled by a cascade of reactions. In each of these steps, protein molecules, called enzymes, take part. Each enzyme affects its small area. And in this case, the ink in the printer is replaced by these enzymes.
To test the effectiveness of the reactions, the printer was charged with a number of enzymes. Then the results were displayed on paper - so the scientists saw which ratios of which enzymes worked more efficiently.
Then another test was carried out: glucose and a substance called ABTS were placed in a purple cartridge, in yellow there was glucose oxidase, in blue there was horseradish peroxidase. When all the elements were mixed, gluco-oxidase removed hydrogen from glucose and added oxygen to it, forming hydrogen peroxide. After that, horseradish peroxidase reacted with ABTS, with the result that the color on the paper turned green.
So scientists have already proven that refilling printer cartridges with the correct enzymes can show glucose levels. Urinary glucose is an indicator of diabetes, so this chemical laboratory based on an inkjet printer has the potential to diagnose this disease. The research results were published in the journal Chemical Communications.
