Abstract
Natural-based macromolecules have been used in the biomedical area, namely in supports for tissue engineering or in the controlled delivery of therapeutic molecules. They can be also combined with inorganic biomaterials, such as bioactive glass/ceramic nanoparticles, to improve their mechanical properties and be directed towards specific orthopaedic applications, as they can exhibit the ability to promote the deposition of bone-like apatite. In our research group different processing and modification strategies have been proposed to use such materials in different shapes (e.g. particles, fibres, membranes, scaffolds) or in the form of hydrogels. We have been using bio-inspired strategies to develop technologies to process new biomedical devices, such as with the use of superhydrophobic surfaces to fabricate hydrogel particles for a variety of applications in biomedicine. Moreover, the right spatial combination of cells and biomaterials could be used to recapitulate some organizations found in native tissues in order to develop better hybrid constructs for advanced therapies. Examples are shown on the development of liquefied capsules containing cells and solid microparticles that allow for a spatiotemporal free-organization of the cells towards the formation of new microtissues. More cases are shown where the combination of principles such as nanotechnologies, bottom-up tissue engineering and hierarchical organizations are used to obtain multi-functional structures to be used in regenerative medicine. free-organization in the space of the cells towards the formation of new microtissues.
