Nowadays, drug delivery has an important role in medical therapy. The use of biopolymers developing systems (DDSs) is increasingly attracting attention due to their remarkable and numerous advantages, contrast conventional polymers. Biopolymers have many advantages (biodegradability, biocompatibility, renewability, affordability, availability), which are extremely for materials with applications the biomedical field. Additionally, appropriate when they improve functioning a number positive...
The article focuses on the optimization of extraction process biologically active compounds (BAC) from grape marc—a by-product wine industry. influence temperature, specifically 30 °C, 45 °C and 65 ethanol concentration in solutions, 0–96% (v/v) yield polyphenols, flavonoids, tannins anthocyanins, were investigated. composition individual anthocyanins organic acids, antioxidant activity (DPPH ABTS) CIELab chromatic characteristics marc extracts (GME), characterized. microbiostatic...
Abstract This study is focused on the determination of some important antibiotics from different classes in waste water samples using solid phase extraction followed by high performance liquid chromatography with two detectors, diode array and mass spectrometer positive ionisation mode. The investigated include three penicillins (amoxicillin, ampicillin, penicillin G), cephalosporins (ceftazidime, ceftriaxone), tetracyclines (tetracycline, doxycycline). studied were extracted...
Two types of magnetite (Fe3O4) nanoparticles were investigated as adsorbents for the simultaneous removal Pb(II), Cd(II), and As(III) metal ions from aqueous solution. Magnetite prepared by two synthesis procedures, both using water solvent, are referred to conventional Fe3O4 green nanoparticles. The latter used Citrus limon (lemon) peel extract surfactant. Box–Behnken experimental design was investigate effects parameters such initial concentration (20–150 mg L−1), pH (2–9), biomass dosage...
In this study the adsorption and photodegradation capabilities of modified multi-walled carbon nanotubes (MWCNTs), using tartrazine as a model pollutant, is demonstrated. MWCNT-COOH/Fe3O4 MWCNT-COOH/Fe3O4/NiO nanocomposites were prepared by precipitation metal oxides in presence MWCNTs. Their properties examined X-ray diffraction powder (XRD), Fourier-transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), scanning (SEM), Raman spectroscopy, synchrotron-based...
Chronic wounds are a major health problem, affecting millions of people worldwide. Resistance to treatment is frequently observed, requiring an extension the wound healing time, and improper care can lead more problems in patients. Smart dressings that provide controlled drug release significantly improve process. In this paper, alginate beads with white lily leaf extract were prepared tested for chronic healing. The obtained characterized by scanning electron microscopy (SEM) Fourier...
The widespread worldwide use of antibiotics leads to significant diffuse pollution the environment, but understanding effects many important on plants is still limited. This study aimed gain insight into impact ampicillin (AMP) and ciprofloxacin (CIP) bioactive compounds, antioxidant capacity, elemental content lettuce (Lactuca sativa L.). was grown in a climate chamber under controlled conditions light temperature, soil with contaminated different concentrations (7.5 mg kg−1—AMP I; 15 II;...
Water contamination is a ubiquitous issue for all countries and territories worldwide. Among others, pesticides, drugs, heavy metals, phosphates play special role in terms of pollutants due to their toxicity large-scale applications industrial agricultural activities. In order provide cleaner freshwater the world’s population, two types actions are required: preventing/limiting pollution that might occur during our daily activities decontaminating already exposed/contaminated water sources....
In this data article, we present supplementary related to the research article entitled "Starch-coated green synthesized magnetite nanoparticles for removal of textile dye Optilan Blue from aqueous media" Stan et al., 2019. Data interpretations are included in The starch-coated Fe3O4 (ST-coated NPs) were analyzed by scanning electron microscopy (SEM) and high resolution transmission (HRTEM) illustrate shape surface coating nanoparticles. Moreover, Brunauer-Emmett-Teller (BET) technique was...
Heavy metals represent a large category of pollutants. are the focus researchers around world, mainly due to their harmful effects on plants. In this paper, influence copper, cadmium, manganese, nickel, zinc and lead, present in soil different concentrations (below permissible limit, maximum concentration higher than limit) lettuce (Lactuca sativa L.) was evaluated. For purpose, authors analyzed variation photosynthetic pigments, total polyphenols, antioxidant activity elemental content...
The article investigated the antioxidant and antimicrobial activity of extracts from two aromatic plants-Satureja hortensis L. (SE) Rosmarinus officinalis (RE), encapsulated in alginate, on-yogurt properties. encapsulation efficiency was controlled by FTIR SEM analysis.
