The softest brain implant ever delivered with a sugar needle

Brain implants are relatively flexible, but still much harder than natural brain tissue. Organism

considers them to be foreign bodies, which causes an inflammatory reaction and the appearance of scar tissue on them. As a result, this interferes with their functioning.

In search of an alternative, scientists from the UniversityMcGill in Canada created a silicone implant, officially called "the softest brain implant in history." It is delivered to the body using a thin needle about 0.2 mm thick. As the authors of the development explain, its consistency resembles a soft pudding.

Since this is an implant, it is very soft and fragile.Routine surgical procedures can damage it. The researchers avoided this problem by placing it in a sugar needle. First, the sugar was melted, then molded and finally allowed to solidify in the shape of a needle. Then the scientists injected liquid silicone into the cavity of the needle, and when it hardened, an implant was formed.

The implants are so soft that the body does not perceive them as a serious threat. It can interact with the brain with the least interference.

Further research will focus on equipping implants with electronics so that they can perform their actual functions.
