Biofunctional polyethylene glycol coatings on titanium: an in vitro-based comparison of functionalization methods
Three methods for the production of Polyethylene glycol (PEG) coatings on titanium are compared, i.e. plasma polymerization, electrodeposition and silanization. The compared deposition methods presented similar wettability (hydrophilic coatings), chemical composition assessed by XPS and thickness ar...

| Sumario: | Three methods for the production of Polyethylene glycol (PEG) coatings on titanium are compared, i.e. plasma polymerization, electrodeposition and silanization. The compared deposition methods presented similar wettability (hydrophilic coatings), chemical composition assessed by XPS and thickness around 1 nm. The coatings lowered albumin adsorption and presented a decreased fibroblast, Streptococcus sanguinis and Lactobacillus salivarius adhesion. Immobilization of a cell adhesion peptide (RGD) presented a higher fibroblast adhesion and no alteration of the bacterial adhesion, giving three methods for the biofunctionalization of titanium for dental implants. The feasibility of each methodology is compared in terms of the process parameters in order to provide a guide for the election of the methodology. |
