Student know how. How saliva can tell you what your body lacks


A large scale initiative competition “Start-up SpbGU-2017” is continuing in St. Petersburg. The team of developers which wins it will get a 1 million ruble price. Second and third place candidates will also be awarded. They will be given 500 and 200 thousand respectively. The ideas could belong to literally any sphere. Mariya Evsyukova spoke to two designers of two unique projects which are in the running for the win and are destined to protect our health


One spit into a vial – and bio material for an express test is ready. Several drops of human saliva are put on a plate with membranes and left for 15 minutes. Then, photos are made and a special program is activated

Darya Dekina, SpbGU student: “This membrane is responsible for sodium, calcium and potassium. We then extract the color components from the photograph which we need, and record it. We have a ready-made calibration on these elements. So we are evaluating the concentration of macro elements in your saliva

The author of the project, Darya Dekina, has proved through experiments that saliva can tell you how much calcium, sodium, magnesium, iron and potassium are there in a human body. The team of scientists has already created a mobile app

Mariya Evsyukova, reporter: “The information is then evaluated by the app, which determines the concentration of elements, and, according to the received data, it would give you recommendations on how you should change your diet to fill the certain elements you lack. In my case, for instance, it recommends to eat more potatoes, apples, seaweed and prunes

Anton Mayevskiy's project also passed the strict jury. His team has taught walls to defend themselves from harmful gas and bacteria. The unique coating was produced with a special device

Anton Mayevskiy, researcher at SpbGU: “On this device we have conducted research of photo active particles which can nullify pollutants in the air. On such surfaces the bacteria will not spread, which will prevent infections and epidemics

The solution will be copyrighted and trademarked. And a number of paint making companies are already interested in it
