Abstract: Increase of surface wettability on glass was observed after atmospheric pressure plasma treatment using two different plasma sources. First used plasma source was Diffuse coplanar surface barrier discharge (DCSBD) and second was commercial gliding arc. [..] Read more

Abstract: The preparation and functionalization of iron oxide magnetic nanoparticles (MNPs) are of great importance in a diverse range of applications. However, their structural and magnetic properties can be influenced by the process of coating making these MNPs undesirable for certain applications. [..] Read more

Abstract: A new nanofibrous membrane with iremarkable chemical and strength properties was prepared through an interaction between polyamide nanofibres and oak bark extract, which is rich in the content of hydrolysable tannins.The aim of this study was to verify the bond strength of tannins and polyamide nanofibres depending on the different pH of the aqueous medium.

Abstract: SPRi (Surface Plasmon Resonance Imaging) biosensors are used for detection in real time with advantage of processing large number parallel measurements. Our goal is fast detection of low concentrations proteins. [..] Read more

Abstract: Hyaluronan as negatively charged polyelectrolyte can interact with positively charged surfactant micelles via electrostatic interactions to form core-shell like nanoparticles. These aggregates can solubilize hydrophobic active substances; therefore, they are potential carriers in drug delivery applications. [..] Read more

Abstract: This paper deals with the fluorescence study of microviscosity changes of hydrogel composed by hyaluronan and cationic surfactant cetyltrimethylammonium bromide (CTAB) during fortnight-ageing. The steady state anisotropy values obtained in the experiments were used to estimate the microviscosity of the corresponding hydrogel regions. [..] Read more

Abstract: During the past few years there has been a remarkable growth of research activities exploring properties and biomedical applications of nano-sized materials. Size, shape, size distribution, morphology, surface functionalization and stability of nanomaterials have an influence on resulting biological and other effects of nanomaterials. [..] Read more

Abstract: Adipose-derived stem cells (ASCs) are of a great importance for bone tissue engineering. We compared ASCs obtained by liposuction under two pressures (-200 mmHg and -700 mmHg). [..] Read more

Abstract: Titanium and its alloys are widely used as hard tissue implants for their high biocompatibility and suitable physical properties. Along with other surface treatment methods, anodization technique is known to enhance osseointegration. [..] Read more

Abstract: In this study the surfaces of pure polyethylene and polyethylene filled with organo-modified vermiculite were prepared and compared. Both polymers were prepared from industrial polyethylene powders. [..] Read more

Abstract: The aim of the presented paper was the investigation of the barrier properties of Diamond Like Carbon (DLC) thin films used for biomedical applications. The DLC films were prepared by the Plasma Enhanced Chemical Vapour Deposition (PECVD) from methane. Stainless steel AISI type 316L was used as a substrate. [..] Read more

Abstract: Bacteria attached to solid surfaces are able to form bacterial biofilms which present serious problems both in healthcare and in industrial applications. Naturally, the development of anti-adhesive coatings that prevent bacterial attachment is of great importance nowadays. [..] Read more

Abstract: This work is focused on exploration of capability of zero charged clay minerals kaolinite and pyrophyllite to carry antibacterial chlorhexidine and antifungal nystatin, respectively. Investigation of host-guest interaction was based on force field molecular dynamics which was performed on model surfaces in periodic boundary conditions. [..] Read more

Abstract: Various carbon nanostructures are widely researched for use in a number of medical applications. We study the surface properties and cell-substrate interactions of amine functionalized carbon nanoparticles (CNPs) grafted on biopolymer film. [..] Read more

Abstract: In recent years, microfluidics has shown considerable promise for improving diagnostics and biology research. Certain properties of microfluidic technologies, such as rapid sample processing and the precise control of fluids in an assay, have made them attractive candidates to replace traditional experimental approaches [1].

Abstract: Biocompatible and bactericidal coatings were deposited onto different titanium based implant materials. For this the plasma chemical oxidation (PCO) process as well as the atmospheric pressure plasma chemical vapour deposition (APCVD) was used successively. [..] Read more

Abstract: Magnetic nanoparticles offer several advantages for isolation of biological materials. Since they are broadly used in diagnostic immunoassays and in various reactions involving enzymes, proteins, and DNA, this study considers the interaction of four surface modified magnetic microparticles with selected DNA fragments.
