Abstract: The present work deals with preparation and subsequent modification of aligned polycaprolactone microfibers made by new semiautomatic drawing technique. This advanced scaffold for tissue engineering combines 3D architecture, large surface area-to-volume ratio, alterable conductivity which closely imitates native extracellular matrix and actively modulating cell functions.

Abstract: One of the most promising type of hybrid nanolayers prepared by sol-gel method are antimicrobial nanolayers based on TMSPM (3-(Trimethoxysilyl)propyl methacrylate) containing ionically bonded cations of silver, copper and zinc. Antimicrobial layer with long-term activity may be applied to the surfaces of almost all materials (metals, glass, ceramics, fabrics, plastics except Teflon). [..] Read more

Abstract: This study is focused on development of novel nanofibrous material with immobilized Ag ions. These nanofibers have a great potential for biomedical applications, especially for antimicrobial wound dressing. [..] Read more

Abstract: Electrospun nanofibers with their nanoscale structure and ability to mimic native extracellular matrix (ECM) harbor a great potential for biotechnology, biomedicine, and tissue engineering. Inorganic nanofibers, such as silica-based nanofibers, have attracted attention for their physical and chemical stability, surface functionalities and hydrophilic nature.In this study, we tested biodegradable SiO2 nanofibers prepared by sol-gel method and needleless electrospinning as a scaffold for human bone marrow mesenchymal stem cells (hMSC), cells which are promising for regenerative medicine.

Abstract: Nanofibers are valued for their ultra-high specific surface areas and have been found potentially useful in many biomedical applications. Modification or functionalization of nanofibers is necessary in order to engineer specific features that will help to maximize their end-use performance. [..] Read more

Abstract: Nanofibers biofunctionalized with enzymes are materials of interest in the biomedical field due to their potential application in wound healing. This work describes the production and characterisation of electrospun chitosan nanofibers biofunctionalized with a microbial collagenase. [..] Read more

Abstract: The aim of the study was to develop a material suitable for wound dressing which would be also suitable for cell growth and cell proliferation. Such matrix should have the structure of interconnected pores and a high porosity to ensure the adequate penetration of the cells and the supply of nutrients to the cells during their formation, diffusion of waste products out of the matrix and exclusion the products of matrix degradation.

Abstract: Submicron particles occurring in the environment are of natural origin, but are also formed by anthropogenic activities as secondary products. The source of these submicron particles are e.g. [..] Read more

Abstract: New nanomaterials are used in nearly every industrial area and provide many benefits. Nevertheless, with new properties of new nanomaterials come new potential risks. [..] Read more

Abstract: Our main objective was to determine the antimicrobial effects of selenium nanoparticles (SeNPs). For the testing of their influence we exploited isolates obtained from swabs from patients (n = 25) with hard-to-heal skin infections. [..] Read more

Abstract: Inorganic nanomaterials have large specific surface area and high bioactivity which made them promising alternatives to the traditional organic antimicrobial agents that are extremely irritant and toxic. In the present report, CdTe/ZnSe core/shell quantum dots (QDs) were conjugated with different nucleobases and their antibacterial activity against Escherichia coli was investigated. [..] Read more

Abstract: Our research is focused on the phase, structure and chemical analysis of the powder particles released by braking of cars from their brake components – discs and pads. The basic information on structure and phase composition was obtained by X-Ray Powder Diffraction, Mössbauer Spectroscopy and scanning electron microscopy with EDX. [..] Read more

Abstract: The growth in the application of nanomaterials (of any structure in any use) leads to increasing concentrations in the environment. These nanomaterials may also enter into wastewater treatment plants and interact with activated sludge, so at least partial knowledge of the behaviour of nanoparticles in the activated sludge is essential.

Abstract: Conformational changes of humic acids in different aqueous solutions were studied by means of two novelty methods: high resolution ultrasound spectrometry (HRUS) and micro-rheology (μR). Obtained results were compared with those of more conventional method of dynamic light scattering (DLS).The HRUS method is based on the measurement of parameters of ultrasonic waves propagating through the sample.

Abstract: Nanofibers are defined as fibres with sub-micron diameter. Due to their thickness they offer extremely large specific surface area. [..] Read more

Abstract: In this paper, magnetic properties and interparticle magnetic interactions of the powder mixtures consisting of a ferromagnetic magnetite (mean particle size about 50 nm) and diamagnetic MgO (micrometric particles) are presented. Mixtures with concentrations of Fe3O4 from 10 to 80 wt. [..] Read more

Abstract: LASER is defined as an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules. It can propagate in a straight line and occur in a wide range of wavelength, energy/power and beam-modes/configurations. [..] Read more

Abstract: The aim of this work was study molecular and quantitative analysis of metal ion binding to humic acids (HAs). The object of our study were two various samples of HAs. [..] Read more
