Abstract: Two antioxidants with relatively strong reducing properties, tannic acid and ascorbic acid, were used for the preparation of the cotton fabric with copper (I) oxide (Cu2O) nanoparticles from cupric ions sorbed into the cotton fabric. Different reducing power of tannic acid and ascorbic acid had an influence on the size of resulting nanoparticles and also on the resulting color of the fabric. [..] Read more

Abstract: Collagen makes up one of the most important parts of the extracellular matrix and connective tissue. Collagen type I accounts for up to 90% of the collagen found in the body and it can be isolated and purified in large quantities and processed into a variety of forms. [..] Read more

Abstract: This paper deals with electrostatic association of cationic micelles (CTAB or Septonex) with hyaluronan. Hyaluronan as negatively charged polyelectrolyte can interact with positively charged surfactant micelles via electrostatic interactions to form nano-core-shell like aggregates. [..] Read more

Abstract: This paper deals with the fluorescence anisotropy study of hydrophobic nanodomains formed by interaction between hyaluronan (Hya) and cationic surfactant cetyltrimethylammonium bromide (CTAB) below critical micelle concentration in aqueous solution and the effect of sodium chloride addition to this system. Hyaluronan as negatively charged polyelectrolyte can interact with cationic surfactants via electrostatic interactions to form aggregates, which could be potential used for targeted drug delivery.

Abstract: Nowadays, biocompatible polymers represent important materials in health-care industry. Their long-term applications, however, lead to the development of infection which must be often suppressed by antibiotic therapy. [..] Read more

Abstract: The present work is focused on preparation of polysaccharide films which were doped with silver nanoparticles for enhancement of antibacterial properties. Silver nanoparticles (AgNPs) were prepared and stabilized by reduction of silver nitrate with chitosan without addition of reducing agents. [..] Read more

Abstract: Polyethylene (PE) is a synthetic polymer used for biomedical applications and tissue engineering. Surface modification of this material relates to changes of its surface hydrophilicity, chemistry, morphology, microstructure, roughness, and topography, all influencing its biological response.

Abstract: Pure silica nanofibers prepared by electrospinning from the sol-gel were reported to be successfully used in tissue engineering due to their biocompatibility, non-toxicity and biodegradability. This study deals with the possible mechanical degradation of silica nanofibers in vitro that have been pulverized down to the size of nanoparticles. [..] Read more

Abstract: Herein we report a theranostic system based on iron oxide-gadolinium nanoparticles coated by chitosan as a dual contrast agent for magnetic resonance imaging and controlled delivery application. Iron oxide nanoparticles were prepared by reduction of iron (III) chloride followed by surface modification using arenediazonium tosylate and diethylenetriaminepentaacetic acid for Gd(III) complexation.

Abstract: Currently, it is well known that metallothioneins (MTs) play substantial role in many pathophysiological processes, including carcinogenesis and they can serve as diagnostic biomarkers. In order to increase the applicability of MT in diagnostics, an easy-to-use and rapid detection method is required. [..] Read more

Abstract: Viral-like particles that express Ebola glycoprotein on surface are very sophisticated and risky techniques for developing diagnostics and study of the virus biology. On the other hand, liposome nanoparticles are easy to prepare and have customized lipid content to encapsulate preferred cargo inside while chemically modified to carry other molecules on their surface.
