Heals wounds with a skin gun

In a new study published in the journal Lab on a Chip, a team of experts from the University of Toronto (Canada) tested the device on small wounds in pigs and mice. The results showed that it was safe, however, this device has not been tested on humans and still in the development phase, DK just said.

Hand-held 3D leather printing device.

A new device like glue gun can print leather with 3D printing technology . Scientists hope it could soon be put to use to heal very deep wounds.

This device weighs less than 0.9kg, can cover a 'bio-ink' slime on the wound surface. This ink contains ingredients often in the skin such as collagen - a protein that helps cells multiply and develop, fibrin - a protein that supports blood clotting to heal wounds. Study co-author Saeid Amini Nik, a cell biologist at the University of Toronto, said: 'I think 3D printers have the potential to create cells, especially to allocate them to create muscles. organism '.

The skin is the largest organ of the body and consists of 3 main layers. The outer layer of the skin, called the epidermis, is made up of dead cells or keratinocytes, which act as a dehydration barrier. This layer also includes lymphocyte immune cells that assist in the eradication of germs, and Merkel cells that give us the ability to sense very light collisions.
