Its delivery method is based on a well-characterized, FDA approved biodegradable chemical platform called PLGA. The company's nanoparticles incorporate a high density of attachment sites on their surface, enabling them to carry out multiple functions--like targeting tumors, enhancing diagnostic images, treating diseased tissue or concealing the whole package from the body's natural defenses.
The company has tweaked the chemical and atomic composition of the raw materials of the glass, which in turn has increased its density -- making it much more scratch and dent resistant than last years model.
Unlike oil, the dye has the same density as the surrounding water, does not coagulate or form slicks, and is not subject to chemical breakdown by bacteria or other forces.
