Dendritic scaffold onto titanium implants. A versatile strategy increasing biocompatibility.

The lack of a relationship between bone cells and metal has traditionally been solved by coating the former with "organic" ceramics, such as hydroxyapatite. A novel approach is hereby presented, immobilizing covalently dendrimeric structures onto titanium implants. Amide-based amino terminal dendrons were synthetized and coupled to titanium surfaces in a versatile and controlled way. The dendritic moieties provide an excellent scaffold for the covalent immobilization of bioactive molecules, such as extracellular matrix (ECM) protein components or antibiotics. Herein, tripeptide arginine-glycine-aspartic acid (RGD) motifs were used to decorate the dendritic scaffolds and their influence on cell adhesion and proliferation processes was evaluated. 2024-02-19T12:40:08Z 2024-02-19T12:40:08Z 2024 2020-04-01 journal article Molina, N.; González, A.; Monopoli, D.; Mentado, B.; Becerra, J.; Santos-Ruiz, L.; Vida, Y.; Perez-Inestrosa, E.
