Scientists have learned to turn on biomedical implants using a smartphone. For this, the authors of the development used a control board capable of generating electric current. Details about the invention writes the journal Science.
Developers from the Swiss Higher Technical School in Zurich have created an implant whose size is no larger than that of a coin. Using a small electric wire, they connected the circuit board to a capsule containing human cells. Using the radio signal created by the smartphone, you can activate the board, which begins to generate current.
In turn, the electric discharge “enlivens” the cells, in the membranes of which potassium and calcium channels are stimulated. They launch a biochemical cascade to regulate the expression of the gene for insulin synthesis. As a result of the work of the implant, insulin accumulates, which consists of the vesicles. And then these vesicles merge with the membrane, and the hormone responsible for the utilization of glucose is released into the body.
According to scientists, diabetics will be able to use such an implant to simplify the administration of drugs, which are now mainly injected into the body through injections. If the patient eats something that increases the level of sugar in his blood, the implanted device automatically activates the production of insulin. Also, this gadget will be able to do a biochemical blood test.
Note that such implants will be a real breakthrough if they go to the mass market. In fact, with their help, you can regulate the work of genes with the help of electrical signals.
