Nanostructured hydroxyapatite powder with biopolymers. Microparticles formed by nanoparticles of hydroxyapatite crystals, with needle shape and stabilized with polymer surfactants, resulting in a structure similar to a blackberry. In the field of regenerative medicine, there is a great use of this biomaterial due to the similarity to the main inorganic constituent of natural bone and teeth. The synthetic hydroxyapatite has excellent biocompatibility and bioactivity to be used as a suitable bone substitute.

This is an embryonic nerve cell growing on DNA. In this system DNA is being studied as a tool to dynamically control surface adhesion for cells. Changing the cell behavior at different time intervals allows us to recreate the dynamic growth sequences that occur naturally in regenerating animals like newts.
