Endor Nanotechnologies is a start up located in Barcelona, devoted to creating new materials based on the use of nanotechnology. The company, formed by 7 people, 5 of them medical researchers, has developed a new material with stunning properties. They have constructed a nano crystal, 1.000 times smaller than the thickness of a hair, using gold atoms precisely arranged, and used this structure to mount on its surface a complex biopolymer which is able to activate the cell mechanisms that regulates self regeneration. This way, they have created a material which is capable to activating the regeneration of biological tissues.
