Abstract: Wear in a friction pair of components of the endoprosthesis has a significant impact on its operational life. The structure of the surface layers of the contacting elements plays a key role in the wear process. [..] Read more

Abstract: The aim of our work was to examine and describe ultrastructure of the agarose hydrogel and any possible structural concentration dependencies, and to assess the distribution and size of pores of agarose hydrogel in dependence on its concentration. Four concentrations were prepared (0.5 %, 1.0 %, 2.0 % and 4.0 % of dry weight content) and cryoSEM and turbidimetry methods were executed on wet (original) samples in order to image the ultrastructure and measure the pore sizes within.Reasonable results were obtained for the wet samples as they were closer to their native state they are usually used for applications in.

Abstract: Platelets are effective source of growth factors and other bioactive molecules. They can be combined with an appropriate scaffold where the mechanical properties of the scaffold and bioactive properties of platelets modulate cell behavior in the site of the injury. [..] Read more

Abstract: Surface-enhanced Raman scattering (SERS) has become an attractive analytical tool for recognition of various biomolecules and bio-objects. In this work, we created a universal platform, based on surface modified gold multibranched nanoparticles (AuMs), plasmon coupling between surface plasmon polariton waves (SPP) and localized surface plasmon (LSP), and utilization of advanced statistical methods for analysis and estimation of SERS spectra, measured on the „tumor“ cells cultivation media.

Abstract: In animal nutrition, the nanotechnology is mostly used for the preparation of nanominerals, especially trace minerals, due to their low bioavailability. These nanominerals also showed advantageous effects at lower doses compared to conventional minerals. [..] Read more

Abstract: Surface-enhanced Raman spectroscopy (SERS), stemming from the gigantic light energy focusing near the plasmon-active surface, provides the possibility to reveal the presence of targeted analytes under extremely dilute conditions. At present, SERS sensors have been making significant progress regarding practical applications in the analytical and bioanalytical fields. [..] Read more

Abstract: Superparamagnetic iron oxides (SPIO) nanoparticles (NPs) are used as negative contrast agents in magnetic resonance imaging (MRI). However, controlled synthesis of highly stable, biocompatible, reproducible SPIO NPs in mild conditions is still very rare which is demonstrated by the fact that many commercial contrast agents have been withdrawn from the market due to the problems with effective and reproducible synthesis.

Abstract: Excellent workability of polymers brings them a considerable potential to be used as matrices for metal nanostructures broadly applicable in medicine. For instance, biologically active metal/polymer composites could be effectively prepared by biocompatible polymer coating by thin metal nanolayers. [..] Read more

Abstract: The easy and fast detection of drug content and concentration levels is demanded in biological research as well as in clinical practice. Here we study on microscopic level how nanodiamonds and gold nanoparticles interact with a multifunctional drug molecule directly on a biosensor surface. [..] Read more

Abstract: Extracts from naturally occurred sources, such as plants or microorganisms, have been recently tested for their interesting properties that can be used in food or cosmetic industry.The aim of this work is to encapsulate microbial compounds, some plant extracts and also model hydrophilic and hydrophobic substances. Chosen components were encapsulated into liposomes.Particle size and distributions of liposomes were analyzed by dynamic light scattering and their stability by using zeta potential. [..] Read more

Abstract: Polycaprolactone is known as biocompatible material for long time and it is considered as possible material for bioscaffolds. Since natural structure of hard tissues (bones) and most of soft tissues (skin, neural tissue) is fibrous, there are attempts to mimic such a structure. [..] Read more

Abstract: The present work is focused on preparation and characterization polysaccharide films based on methylcellulose. Films were doped with silver nanoparticles (AgNPs). [..] Read more

Abstract: Plasma-polymerized organosilicon coatings have been playing an important role in many research studies due to their wide range of applications. These materials can be used in industry as transparent wear resistant layers, protective hard a-Si:C:H or SiO2-like films, corrosion protection coatings, barrier films etc. [..] Read more

Abstract: This is a first report for the synthesis of silver nanoparticles using branch extract of Betula pendula - one of the most common trees in Europe, China and southwest Asia. The present study is dealing with ecofriendly green synthesis of silver nanoparticles (AgNPs) using the aqueous extract of branches from B. [..] Read more

Abstract: Prevention of the non-specific adhesion of bacteria, cells or proteins to a solid surface is essential for sustaining the functionality and stability of medical implants. Poly(2-oxazolines) (POx) are a class of synthetic polymers, which among other features (e.g., biocompatibility, water solubility) possess anti-biofouling properties and accordingly, they are very promising for this purpose.

Abstract: In this work, silica dioxide nanofibers (SiNFs) were prepared by sol-gel method followed by electrospinning to be further functionalized by silanization. To improve the chemical modification, plasma treatment of various parameters was applied and the effect on the surface properties before and after plasma activation was studied. [..] Read more

Abstract: PDMS microchambers and microchannels were evaluated in many studies of the specific in vitro cultivation. Modern microtopographical methods bring new possibilities how to prepare transparent planar blocks with isotropic lamellas. [..] Read more

Abstract: Interaction between engineered nanoparticles and plants is still a widely unexplored area. While there is a growing body of research on the toxicity of nanoparticles to plants, their stress-inducing capabilities are less known. [..] Read more

Abstract: A firearm shot is a complicated physico-chemical process in where the by-product of the shot is a shot-fire product that contains both metallic and non-metallic micro and nanoparticles. The main aim of the experiment was to verify the efficiency of respirators against gunshot residues from pistol shooting on an indoor shooting range and testing the phytotoxicity of sediment particles taken from the shooting range floor.
