Abstract: At present, treatment of surface, underground and waste water is viewed as a high priority and many studies deal with this issue. Water can be contaminated by organic pollutants, inorganic pollutants, toxic, heavy metals and their compounds, and many other substances that do not degrade to non-toxic compounds in natural waters.

Abstract: Heavy metals are widely used in a range of materials including paints, motor vehicles, guns, and electrical components. After discarding such materials, the metal ions after dissolution can penetrate to the environment and are toxic to plants, organisms, and humans. [..] Read more

Abstract: The plasma enhanced chemical vapour deposition was combined with in situ deposition of Ge and Sn thin film by evaporation technique at surface temperature about 220 °C to form nanoparticles on the surface of hydrogenated silicon thin films to prepare diodes. Formation of nanoparticles was additionally stimulated by plasma treatment through a low pressure hydrogen glow discharge. [..] Read more

Abstract: Solid phase microextraction has been established as modern analytic method, which provides several benefits such as sensitivity, rapid and solvent free technique for sample preparation in organic analytical chemistry. Nowadays there is a scientific effort dedicated to improve analytical methods based on new and nanostructured materials. [..] Read more

Abstract: In this work the function and application of titanium dioxide as a filler in a composite system polycaprolactone/titanium dioxide (PCL/TiO2) was examined. Titanium dioxide was applied by ultrasonic bath on already electrospun PCL fibrous scaffold treated and non-treated with NaOH. [..] Read more

Abstract: Polyelectrolyte-surfactant mixtures are progressive systems studied for their potential use in numerous applications in daily life including delivery systems for pharmaceutics. Mixing polyelectrolytes with oppositely charged surfactant ions in aqueous media typically leads to a strong association providing a simple route for constructing ordered materials with a great scientific and application potential.

Abstract: The presented work was focused on the study of interactions of azo dyes (model diffusion probes) with cationic biopolymer chitosan. The interactions were realized via diffusion processes in hydrogel media based on thermoreversible agarose. [..] Read more

Abstract: The aim of this study was to describe electrospinning method for preparation of self-supporting homogenous nanofibrous layers with a presence of pristine clay minerals and clay minerals containing antibacterial agent chlorhexidine acetate in their interlayer space. One clay and two polymers were used. [..] Read more

Abstract: At present, great attention is given to silver nanoparticles (AgNPs), which thanks to its unique properties, such as good electric conductivity, photoelectrochemical activity and antimicrobial activity are widely used. Green synthesis of nanoparticles uses biological molecules from living organisms. [..] Read more

Abstract: Sarcosine oxidase (SOX) is an enzyme that catalyzes the oxidative demethylation of sarcosine with the glycine as a product and is physiologically active in human body and other mammals. However prostate cancer cells have a high expression of sarcosine. [..] Read more

Abstract: Infectious diseases are known to be a constant threat to human health also in the beginning of the 21st century. The rapid growth of the human population has led to the agricultural intensification, which has caused an increase in resistant bacterial species in the environment. [..] Read more

Abstract: Breast cancer is the most commonly diagnosed cancer in women. Circulating tumor DNA (ctDNA) is related to breast cancer development and thus, screening of tumors using ctDNA blood detection is highly sensitive and may significantly improve early-stage breast tumor diagnosis. [..] Read more

Abstract: Metalothionein (MT) is a polypeptide of molecular weight in the range of 6-10 kDa. MT typically contains 60 to 68 amino acid residues. [..] Read more

Abstract: Composite films based on furcellaran (FUR) and carbon quantum dots (CQDs) has been obtained by casting method. The effects of CQDs films as nanofiller on optical, physical, mechanical and microstructural properties of furcellaran films were evaluated. [..] Read more

Abstract: Zinc phosphate particles were prepared by reaction of zinc nitrate with hydrogen phosphate, diphosphate and triphosphate, and characterized by Dynamic Light scattering (DLS) and Scanning Electron Microscopy (SEM). Antibacterial effect of ZnO nanoparticles and zinc phosphates ones were compared. [..] Read more

Abstract: A sensitive detection of microorganisms plays an important role in prevention and identification of infectious and deadly diseases. However, conventional methods of bacterial detection are time-consuming, laborious or expensive. [..] Read more

Abstract: Histamine, biologically active amine, is normally present in the body and it is involved in a local regulation of physiological processes. It occurs in food as a product of microbial decarboxylation of amino acid histidine, and consumption of histamine-rich food can lead to intoxication. [..] Read more

Abstract: The synthesis of TiO2 nanoparticles (NPs) under various temperature treatments was described and TiO2 NPs was subsequently tested as an antibacterial agent. Scanning electron microscopy (SEM), Raman spectroscopy, Dynamic light scattering (DLS) were used to confirm structure of TiO2 NPs and detect differences between individual batches treated with different temperature. [..] Read more

Abstract: Phytoestrogens are assumed to play an important role in the prevention of tumor or heart disease, and osteoporosis. Soy food is the most significant source of these compounds present as acetylglucosides, malonylglucosides and/or methyl ethers. [..] Read more

Abstract: Given the miRNA-34 family role as tumor suppressor in cancer, it was showed that using miRNA-34a as a new anticancer agent has a great therapeutic potential. Unfortunately, biopharmaceutical issues, rapid degradation in biological fluids, poor uptake into cells and not specific distribution into the body, prevent the use of wild-type non-coding RNA by systemic administration.
