Pectin-decorated magnetite nanoparticles as both iron delivery systems and protective matrices for probiotic bacteria

The goal of this work was to investigate biophysical stability of iron-pectin nanoparticles and analyze the feasibility of using them as delivery systems for the probiotic strain Lactobacillus plantarum CIDCA 83114. Iron oxide (Fe 3 O 4 ) …

pH and ion-selective swelling behaviour of keratin and keratose 3D hydrogels

The oxidation of keratin hydrogels was optimized aiming to obtain keratose hydrogels while maintaining the original 3D structure and pH-responsive behaviour. In addition, we present a comparative study of their dual-stimuli responsive behaviour …

Smart release of antimicrobial ZnO nanoplates from a pH-responsive keratin hydrogel

A smart antibacterial biomaterial based on a keratin hydrogel with pH-dependent behavior and Zinc Oxide nanoplates as biocide agent has been developed. The pH of a chronic wound is basic due to bacterial metabolism. Originally shrank at acid pH, …

Calcium alginate beads reinforced with synthetic oligomers, linear polyethylenimine and Cu(II): structural stability and potential applications

Calcium alginate beads were reinforced with linear polyethylenimine (PEI), Cu(II) and synthetic oligomers derived from a diepoxide, methacrylic acid and imidazole, to increase the resistance to stirring and vibration for environmental applications. …

Carbon quantum dot surface-chemistry-dependent ag release governs the high antibacterial activity of Ag-metal-organic framework composites

Nanocomposites and hybrid materials of Ag-1,3,5- benzenetricarboxylic acid metal-organic frameworks (MOFs) with Sand N-carbon quantum dots (CQDs) were synthesized and evaluated for their antibacterial activity against representative Gram-positive …

Continuous flow adsorption of ciprofloxacin by using a nanostructured chitin/graphene oxide hybrid material

A novel nanostructured material was successfully developed by combining a chitin matrix with graphene oxide nanosheets (Chi:nGO) and then used for the continuous flow adsorption of ciprofloxacin. The spectroscopic characterization indicated that none …

Enhanced electrochemical response of carbon quantum dot modified electrodes

A glassy carbon electrode (GCE) was surface-modified with carbon quantum dots (CQDs) and applied for the effective enhancement of the electrochemical signal for dopamine and uric acid determination. CQDs were prepared from graphite by a green …

Generation and Stability of the gem-Diol Forms in Imidazole Derivatives Containing Carbonyl Groups. Solid-State NMR and Single-Crystal X-ray Diffraction Studies

The stability of gem-diol forms in imidazolecarboxaldehyde isomers was studied by solid-state nuclear magnetic resonance (ss-NMR) combined with single-crystal X-ray diffraction studies. These methodologies also allowed determining the factors …

Influence of GO reinforcement on keratin based smart hydrogel and its application for emerging pollutants removal

In this work, the influence of graphene oxide (GO) reinforcement on keratin based smart hydrogel and its application for the emerging pollutant ciprofloxacin removal was studied. Firstly, the obtained material was characterized by Infrared …

Solar light efficient photocatalytic activity degradation of emergent contaminants by coated TiO2 nanoparticles

The photocatalytic degradation of different emergent contaminants in aqueous solutions has been studied by using oligomer-coated TiO2 nanoparticles under solar light irradiation. The oligomer was synthesized using methacrylic acid, ethylene glycol …
