Currently wounds and cuts are closed using silk sutures or small plastic and metal clasps, but their marks can remain forever and in certain cases cause long-term inconvenience for patients. To avoid them, in cosmetic surgery special adhesives are often used to hold the tissues together, but they tend to make body with the skin and sometimes present toxicity.
Researchers from the Technion-Israel Institute of Technology have created a soft biocompatible glue and a special glue gun that can quickly and easily close wounds without side effects.
Surgical glue is made up of modified molecules of (take a breath) polycaprolactone, a biocompatible material that melts at low temperatures and remains soft even at room temperature. Just like with silicone guns, the material is inserted as a stick into the device and then "fired" into the wound. It is just that: a glue to suture wounds.
An interesting aspect: the density of the "bio glue" can also be modified during preparation to vary its characteristics of fluidity and density, to adapt to the type of skin of the patient or the type of wound.
The first in vitro and in vivo experiments (on animals) of suturing with glue showed complete biocompatibility, safety and efficacy.
