Chitosan acquires bacteriostatic properties via protonation of its amino groups. However, much the literature assumes that chitosan itself inhibits growth bacteria. This article presents a comparative study nonwovens modified with various acids, including acetic, propionic, butyric, and valeric organic as well hydrochloric acid. The aim was to determine which acid salts influence antibacterial antifungal activity chitosan-based materials. Two methods were used modify (formation ammonium...
This paper presents a comparative study on chitosan degradation in organic acid solutions according to their different dissociation characteristics. More precisely, the aim of was determine kinetics process depending constants (pKa values). The scientists involved date have focused mainly acetic solutions. Solutions lactic, acetic, malic, and formic acids concentrations 3% wt. were used this research. progress determined based intrinsic viscosity measurement, GPC/SEC chromatographic...
The growth of population and increase in diseases that cause an enormous demand for biomedical material consumption is a pointer to the pressing need develop new sustainable biomaterials. Electrospun materials derived from green polymers have gained popularity recent years applications such as tissue engineering, wound dressings, drug delivery. Among various bioengineering used synthesis biodegradable polymer, poly(lactic acid) (PLA) has received most attention researchers. Hypericum...
In the interests of using green and sustainable chemical innovations to create products with minimized (or no) hazard potential, polyester fabric in this work was activated functionalized chitosan its durability investigated. Chitosan is a natural biopolymer derived from chitin. As it has good biocompatibility, bio-absorption, anti-infectious, antibacterial hemostatic properties accelerates wound healing, increasingly being researched for antimicrobial treatment textiles. Due increased...
New scaffold materials composed of biodegradable components are great interest in regenerative medicine. These should be: stable, nontoxic, and biodegrade slowly steadily, allowing the stable release biologically active substances. We analyzed peptide-polysaccharide conjugates derived from peptides containing RGD motif (H-RGDS-OH (1), H-GRGDS-NH2 (2), cyclo(RGDfC) (3)) polysaccharides as scaffolds to select most appropriate biomaterials for application Based on results MTT Ki-67 assays, we...
This work presents the results of research on obtaining chitosan (CS) films containing their surface ciprofloxacin (CIP). A unique structure was obtained that not only gives new properties to films, but also changes way coverage and surface. The spectroscopic test showed in process application CIP CS film, converted from its crystalline form an amorphic one, hence improving bioavailability. improved scope microbiological effect. carried out reduction concentration during adhesion films....
The DSC measurements were made in the Institute of Material Science Textiles and Polymer Composites at Faculty Technologies Textile Design, Lodz University Technology.
Obliczenia funkcjonalu kwantowo-chemicznego (DFT) wskazują, ze wartośc energii reorganizacji wskazuje na mozliwośc efektywnego wychwytywania dziur przez cząsteczke antronu podczas transportu nośnikow ladunku. Badania metodą roznicowej kalorymetrii skaningowej (DSC) wskazują stabilnośc temperaturową cząsteczek powyzej temperatury topnienia do 164oC. Temperature zeszklenia określono jako Tg = 153,7°C, a temperature Tc 157,05°C.
