One aspect of the present disclosure can include a thermoresponsive nanocomposite for disrupting or preventing biofilm formation. The nanocomposite can include at least one polymer, one or more D-amino acids, and one or more energy-actuatable particles. The nanocomposite can have a first viscosity at about room temperature and, when exposed to about physiological temperature, obtains a second viscosity that is greater than the first viscosity. Application of energy to the nanocomposite from an energy source can excite the one or more energy-actuatable particles to cause localized heat release from the nanocomposite.

An orthopaedic prosthesis includes a femoral component comprising polymeric materials. The polymeric materials may include a polyaromatic ether or a polyacetal. The orthopaedic prosthesis may include a component having an articular layer and a support layer adjacent the articular layer. The support layer may include a reinforcement fiber. The orthopaedic prosthesis may be a knee prosthesis.

Disclosed is a scaffold for living donor transplantation, which includes sintered bioglass and a biocompatible polymer and has improved properties using a 3D printer through a fused deposition modeling process.

A bone graft for bone repair, the bone graft having controlled release bone mineral ions includes a resorbable polymer incorporated with a bone mineral ion donor to form a mineral-incorporated resorbable polymer, and demineralized bone matrix (DBM) mixed with the mineral-incorporated resorbable polymer.

An oxygen-releasing biomaterial, articles and methods, and more particularly an oxygen-releasing biomaterial with sustained oxygen-releasing properties of four to five weeks, which is suitable for tissue engineering scaffolds, is disclosed. The biomaterial contains a hydrogel with a plurality of microparticles suspended in the hydrogel. The microparticles contain an oxygen carrier that is encapsulated in a biocompatible hydrophobic material, where the release of oxygen from the oxygen carrier is sustained over a four to five week period. The biomaterial has application in tissue engineering, osteogenesis, burn and wound treatment, and treatment of cardiac conditions, and has further antimicrobial properties.

The present invention relates to an extrudable photocrosslinkable hydrogel comprising a biochemically modified extracellular matrix (ECM) with an electroconductive nanomaterial embedded; a photoinitiator and a solvent, the method for its preparation starting from decellularized extracellular matrices (dECMs) and its applications for preparing electroconductive scaffolds, electroconductive extrudable hydrogels for in situ defect-filling, conductive grafts, in situ or in vitro printed tissues or organs, adhesives for different tissues, or bone adhesives.

Compositions useful as bone fillers or dental composites are provided which may include a sterilizing agent.
