ZnO-modified cellulose fiber sheets for antibody immobilization
(Elsevier Sci Ltd, Oxford, 2014)
Cellulose fiber sheets impregnated with saccharide capped-ZnO nanoparticles were used as bioactive materials for antibody immobilization. First, ZnO nanoparticles were synthesized in the presence of glucose (monosaccharide), ...
Design of pectin-sodium alginate based films for potential healthcare application: Study of chemico-physical interactions between the components of films and assessment of their antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2017)
In this study, pectin based films including different amounts of sodium alginate were prepared by casting method. All the films, with and without polyglycerol as plasticizer, were crosslinked with zinc ions in order to ...
Antioxidant edible films based on chitosan and starch containing polyphenols from thyme extracts
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to analyse the antioxidant activity of different polymeric matrices based on chitosan and starch, incorporating a thyme extract (TE) rich in polyphenols. TE provided the films with remarkable ...
Molecular weight distribution and functional group profiles of TEMPO-oxidized lyocell fibers
(Elsevier Sci Ltd, Oxford, 2013)
The effects of TEMPO-mediated oxidation, performed with NaClO, a catalytic amount of NaBr, and 2,2',6,6'-tetramethylpiperidine-1-oxy radical (TEMPO), were studied on lyocell fibers by means of GPC using multiple detection ...
Impregnation of cotton fabric with silver nanoparticles synthesized by dextran isolated from bacterial species Leuconostoc mesenteroides T3
(Elsevier Sci Ltd, Oxford, 2015)
This study was aimed to highlight the possibility of cotton fabric impregnation with silver nanoparticles synthesized by dextran isolated from Leuconostoc mesenteroides T3 in order to obtain antimicrobial properties. The ...
A comprehensive approach to in vitro functional evaluation of Ag/alginate nanocomposite hydrogels
(Elsevier Sci Ltd, Oxford, 2014)
In this work, we present a comprehensive approach to evaluation of alginate microbeads with included silver nanoparticles (AgNPs) at the concentration range of 0.3-5 mM for potential biomedical use by combining cytotoxicity, ...
Achieving high antimicrobial activity: Composite alginate hydrogel beads releasing activated charcoal with an immobilized active agent
(Elsevier Sci Ltd, Oxford, 2018)
New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. ...
Antibacterial activity of Cu-based nanoparticles synthesized on the cotton fabrics modified with polycarboxylic acids
(Elsevier Sci Ltd, Oxford, 2018)
The fabrication of antimicrobial textile nanocomposite by in situ synthesis of Cu-based nanoparticles on cotton fabrics modified with different polycarboxylic acids was discussed in this study. In order to evaluate the ...
Alginate/soy protein system for essential oil encapsulation with intestinal delivery
(Elsevier Sci Ltd, Oxford, 2018)
Preparation of alginate-soy protein isolate (AL/SPI) complex beads containing essential oil of thyme was carried out by emulsification of thyme oil in aqueous sodium alginate solution blended with SPI solution, followed ...
Antibacterial ability of immobilized silver nanoparticles in agar-agar films co-doped with magnesium ions
(Elsevier Sci Ltd, Oxford, 2019)
The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components ...
