Chitosan-vanillin composites with antimicrobial properties
Marta Stroescu,Anicuta Stoica-Guzun,Gabriela Isopencu,Sorin Ion Jinga,Oana Cristina Parvulescu,Tanase Dobre,M. Vasilescu +6 more
TL;DR: In this article, the authors described the obtaining and characterization of composite films containing chitosan, vanillin and Tween 60, which have been characterized by various methods like Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD), and solid state 13C nuclear magnetic resonance (CP/MAS 13C NMR).
Journal ArticleDOI
Bacterial cellulose films with ZnO nanoparticles and propolis extracts: Synergistic antimicrobial effect
Alexandra Mocanu,Gabriela Isopencu,Cristina Busuioc,Oana-Maria Popa,Paul Dietrich,Liana Socaciu-Siebert +5 more
TL;DR: The antimicrobial synergistic effect of the BC-ZnO-propolis films were evaluated against Escherichia coli, Bacillus subtilis, and Candida albicans and revealed that BC- ZnO had no influence on Gram-negative and eukaryotic cells.
Journal ArticleDOI
Biocompatible pure ZnO nanoparticles-3D bacterial cellulose biointerfaces with antibacterial properties
Valentina Dinca,Alexandra Mocanu,Gabriela Isopencu,Cristina Busuioc,Simona Brajnicov,A. Vlad,Madalina Icriverzi,Madalina Icriverzi,A. Roseanu,Maria Dinescu,Marta Stroescu,Anicuţa Stoica-Guzun,Mirela Petruta Suchea +12 more
TL;DR: In this paper, the authors obtained and characterized a new antibacterial and biocompatible nano-ZnO-bacterial cellulose (BC) material with controlled interfaces for studying in vitro microorganisms (Escherichia Coli (ATCC 8737), B. subtilis Spizizenii Nakamura(ATCC 6633), Candida albicans (AT CC 10231), and mammalian cells (human dermal fibroblast cells) response.
Journal ArticleDOI
Drug release kinetics from carboxymethylcellulose-bacterial cellulose composite films.
TL;DR: The release kinetic of Ibuprofen sodium salt was described using a model which neglects the volume expansion due to polymer swelling and which considers non-linear diffusion coefficients for drug and solvent, and the drug release rate was decreasing with the increase of BC content.
Journal ArticleDOI
Optimization of ultrasound and microwave assisted oil extraction from sea buckthorn seeds by response surface methodology
Gabriela Isopencu,Marta Stroescu,Alma Brosteanu,Nicoleta Chira,Oana Cristina Pârvulescu,Cristina Busuioc,Anicuta Stoica-Guzun +6 more
TL;DR: In this article, two modern methods of sea buckthorn seed oil extraction, ultrasound assisted extraction (UAE) and microwave assisted extraction, were described and compared with conventional oil extraction.
