New implants for the treatment of infections and bone tumours

Researchers of Unit 26 of NANBIOSIS participate in the design and evaluation of the cellular level of a new hybrid material for the creation of intelligent-scaffolds implants that open the door to a more efficient treatment of infections and bone tumors.

The main novelty is the incorporation of a mesoporous matrix of silicon, calcium and phosphorus oxides, with molecular gates that would allow the controlled release of substances stored inside the pores, such as antitumor drugs or antibiotics. A molecular gate is a mechanism whose opening depends on certain external stimuli, in this particular case the drugs would only be released in the presence of enzymes associated with a tumor or a infection in the bones.Nowadays there are scaffolds that allow the slow release of a drug, but this is produced automatically and non-specific.

Molecular gates have been characterized by the use of the Nuclear Magnetic Resonance Unit 26 of NANBIOSIS
