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 ...
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, ...
Response surface methodology for optimisation of edible coatings based on dextran from Leuconostoc mesenteroides T3
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this study was to develop dextran-based edible films plasticized by sorbitol. In order to optimise the film-forming formulation, response surface methodology was used. The influence of dextran and sorbitol ...
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 ...
Sorption properties of TEMPO-oxidized natural and man-made cellulose fibers
(Elsevier Sci Ltd, Oxford, 2009)
Cotton and lyocell fibers were oxidized with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO), under various conditions. Water-insoluble fractions, collected ...
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 ...
Viscoelastic properties and antimicrobial activity of cellulose fiber sheets impregnated with Ag nanoparticles
(Elsevier Sci Ltd, Oxford, 2012)
A silver nanoparticle colloid was prepared by a modified Tollens method using D-glucose as the reduction agent. The obtained nanoparticles were used for the modification of pine, linter and recycled cellulose fibers. ...
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 ...
