Electronically non-adiabatic influences in surface chemistry and dynamics.
Electronically nonadiabatic interactions between molecules and metal surfaces are now well known. Evidence is particularly clear from studies of diatomic molecules that molecular vibration can be strongly coupled to electrons of the metal leading to efficient energy transfer between these two kinds of motion. Since molecular vibration is the same motion needed for bond breaking, it is logical t...
متن کامل2 Surface biocompatibility
The surface is of critical importance in determining the in vivo performance and acceptance of an implant, with respect to both tissue and blood. Material surface properties have been studied intensively, but only in recent years have quantitative, mechanistic links been made to biomolecular and cellular interactions driven by the surface. This review focuses mainly on polymeric surfaces both b...
متن کاملRegulating Biocompatibility of Carbon Spheres via Defined Nanoscale Chemistry and a Careful Selection of Surface Functionalities
A plethora of nanoarchitectures have been evaluated preclincially for applications in early detection and treatment of diseases at molecular and cellular levels resulted in limited success of their clinical translation. It is important to identify the factors that directly or indirectly affect their use in human. We bring a fundamental understanding of how to adjust the biocompatibility of carb...
متن کاملSurface chemistry effects of topographic modification of titanium dental implant surfaces: 1. Surface analysis.
PURPOSE To analyze the surface composition of 34 different commercially available titanium dental implants. MATERIALS AND METHODS Surface composition was evaluated by x-ray photoelectron spectroscopy (XPS). Samples were divided into 4 groups, depending on their surface topography (machined, sandblasted, acid etched, or plasma sprayed). RESULTS Statistical analysis of the data showed a clear...
متن کاملMolecularly engineered p(HEMA)-based hydrogels for implant biochip biocompatibility.
The strategy of phospholipid-based biomimicry has been used to molecularly engineer poly(2-hydroxyethyl methacrylate) [p(HEMA)]-based hydrogels for improved in vitro and potential in vivo biocompatibility. Two methacrylate-based monomers, poly(ethylene glycol) (200) monomethacrylate (PEGMA) and 2-methacryloyloxyethyl phosphorylcholine (MPC), were incorporated at varying mole fractions of 0.0-0....
