Multiple biological, synthetic and hybrid polymers are used for multiple medical applications. A wide range of different polymers is available, and they have further the advantage to be tunable in physical, chemical and biological properties in a wide range to match the requirements of specific applications.

"These are long-chain polymers, which look like cooked spaghetti noodles at a molecular level," he says. "You can make these cooked spaghetti noodles more rigid, and in so doing you create spaces.

The wavenumber of the particle should be controllable by changing the size of the particles used to coat the surface," which determines the color emitted. While Takasu could easily react the non-ionic.

But, Yang said, when those tissues grow into the fluorescent biomaterial, their interaction may change the fluorescent. "We can even make our polymers with extra bonding sites on the surface," Yang.
