Chemical analyses of hydroxyapatite formation on SAM surfaces modified with COOH, NH2, CH3, and OH functions
Hydroxyapatite formation SAM surfaces Surface plasmon resonance
2010/11/29
Hydroxyapatite formation was examined at the surface of self-assembled monolayers (SAMs) modified with four functional groups, -COOH, -NH2, -CH3, and -OH. For COOH-SAM and NH2-SAM, scanning electron s...
Characterization of titanium surfaces for dental implants with inorganic contaminant
Titanium Dental implants Aluminum oxide Image processing computer-assisted
2009/10/19
