Here we show that the efficacy of chitosan interaction with diglycidyl ethers glycols significantly depends on pH and nature acid used to dissolve chitosan. In solutions hydrochloric acid, cross-linking ethylene glycol (EGDGE) polyethylene (PEGDGE) at room subzero temperatures yields mechanically stable gels cryogels, while in acetic only weak can be formed under same conditions. A combination elemental analysis, FT-IR spectroscopy, solid state 13C 15N NMR spectroscopy was elucidate possible...
Abstract In this study the flocculation efficiency of cationic starch derivatives varying degrees substitution (DS) and different amylose/amylopectin ratios was investigated compared to structural properties. The molar masses, M w , radii gyration, R G mass distributions samples were determined by applying method flow field‐flow‐fractionation combined with multi‐angle light scattering interferometric refractometry. dewatering experiments potato differing DS have optimum dosages that...
Chitosans are natural aminopolysaccharides, whose low cytotoxicity suggests their potential use for nonadhesive, antibacterial coatings on biomaterials implant surfaces. Here, the antiadhesive behavior and ability to kill bacteria upon adhesion ("contact killing") of chitosan were evaluated two strains Enterococcus faecalis, isolated from clogged biliary stents. Chitosan covalently grafted or applied as chitosan/κ-carrageenan multilayers characterized by ellipsometry, scanning force...
All-dielectric resonant nanostructures made of high-index dielectrics have recently emerged as a promising surface-enhanced Raman scattering platform which can complement or replace the metal-based counterparts in routine sensing measurements.
We report an easy-to-implement device for surface-enhanced Raman scattering (SERS)-based detection of various analytes dissolved in water droplets at trace concentrations. The combines analyte-enrichment system and SERS-active sensor site, both produced via inexpensive high-performance direct femtosecond (fs)-laser printing. Fabricated on a surface water-repellent polytetrafluoroethylene substrate as arrangement micropillars, the supports evaporating droplet Cassie–Baxter superhydrophobic...
Detection of nitroaromatic compounds (NACs) is an important applied task for environmental monitoring, medical diagnostics, and forensic analysis. However, detection NAC vapors challenging owing to their low vapor pressure relatively weak sensitivity the existing techniques. Here, we propose a novel concept design fluorescence (FL) platforms based on chemical functionalization nanotextured dielectric surfaces exhibiting resonant light absorption, trapping, localization effects. We...
Here, we report a new simple and fast method of cobalt copper ferrites film fabrication on the Ti/TiO2 surface. The approach is based deposition gelatin gel containing nitrates surface porous oxide-silicon coatings titanium obtained by plasma electrolytic oxidation (PEO) followed two-stage annealing at 300 °C 800 to yield ferrite films with good adhesion PEO layer. presence Co/Cu phases was confirmed EDX analysis, XRD, Mössbauer spectroscopy. TiO2-CoFe2O4 TiO2-CuFe2O4 composite have...
Cross-linking chitosan at room and subzero temperature using a series of diglycidyl ethers glycols (DEs)—ethylene glycol (EGDE), 1,4-butanediol (BDDE), poly(ethylene glycol) (PEGDE) has been investigated to demonstrate that DEs can be more powerful alternative glutaraldehyde (GA) for fabrication biocompatible cryogels with tunable properties. Gelation was significantly slower than GA, allowing formation larger pores higher permeability, suitable flow-through applications cell culturing....
Abstract Summary: Growing demand for environmentally friendly technologies promotes the interest in investigation of natural flocculants and development new ways their derivatization aimed to find a compromise between cost, efficiency, safety polyelectrolyte applications. Recent progress cationization starch [T. Heinze et al., Macromol. Mater. Eng . 2002 , 287 495] allowed obtaining cationic derivatives (2‐hydroxy‐3‐trimethylammoniumpropyl chloride) with very high substitution degrees (up...
