The functionalization of biomaterial surfaces for the design and exploration of novel properties has attracted increasing attention in research. In the field of dentistry, fighting bacterial colonisation is largely associated to the use of antibiotics. More recently, the deposition of coatings on dental implants by wet chemical processes has been s...

A low pressure plasma process based on plasma deposition has been used todevelop a drug delivery strategy. In this study, a drug delivery system based ondifferent layers of plasma co-polymerized Poly ε-caprolactone-Polyethylene glycol(PCL-PEG) co-polymers was deposited on biocompatible substrates. Cis-platinum(118 μgm/cm2) was used as an anti-cance...

Age related macular degeneration of the eye is brought about by damage to the retinal pigment epithelium (RPE) and is a major cause of adult blindness. One potential treatment method is transplantation of RPE cells grown in vitro. Maintaining RPE cell viability and physiological function in vitro is a challenge, and this must also be achieved using...

Organic-inorganic multilayer structures were prepared for a moisture barrier. As the organic polymer and inorganic layers, plasma-polymerized n-hexane and aluminum-oxide layers were utilized, respectively. The plasma polymerization of n-hexane was confirmed by the appearance of carbon double bonds in the produced polymer layer. The organic and inor...

The study describes the preparation and properties of Al/AlxOy nanoparticles and their nanocomposites with hydrocarbon plasma polymer. The nanoparticles were deposited using a simple gas aggregation cluster source based on a planar magnetron. The influence of deposition parameters on size distribution was studied. It was found that Al nanoparticles...

Subretinal transplantation of functioning retinal pigment epithelial (RPE) cells grown on a synthetic substrate is a potential treatment for age-related macular degeneration (AMD), a common cause of irreversible vision loss in developed countries. Plasma polymers give the opportunity to tailor the surface chemistry of the artificial substrate whils...

Thin films of the n-type, organic semiconductor PDI-8CN2 were thermally evaporated on two different dielectric surfaces and their optical and morphological properties investigated using Variable Angle Spectroscopic Ellipsometry (VASE) and Atomic Force Microscopy (AFM), respectively. The two dielectric surfaces used were SiO2 and a plasma polymer de...

If plasma technology can come out of the vacuum chamber and plasma can be extruded through a small pencil-type torch, it can be applied widely to dental practices. For this study, we designed a small pencil-type non-thermal atmospheric-pressure glow discharge plasma torch. The purpose of this study was to determine the effect of plasma polymer coat...

Plasma-polymerised vinyltriethoxysilane (pp-VTES) films with thicknesses ranging from 20 nm to about 5 μm were studied by combined method of spectroscopic ellipsometry and optical reflectivity in VIS and UV spectral zone. For these photon energies Tauc-Lorentz dielectric function (with a band gap of about 2.5 eV) was found to be an appropriate para...
