This work is investigating the chemical grafting on Ti surface of a polymer/calcium phosphate coating of improved adhesion for enhanced bioactivity. For this purpose, a whole new methodology was developed based on covalently attaching a hyperbranched poly(ethylene imine) layer on Ti surface able to promote calcium phosphate formation in a next deposition(More)
To develop a novel hyperbranched polymer-based nanocarrier for efficient drug delivery to cell mitochondria. Also to study for the first time the cytotoxic effect of doxorubicin via mitochondria-specific delivery system. We introduced alkyltriphenylphosphonium groups (TPP) to a poly(ethylene imine) hyperbranched polymer (PEI). We harnessed the hydrophobic(More)
