Osteoblastic cellular responses on ionically crosslinked chitosan-tripolyphosphate fibrous 3-D mesh scaffolds.
Tripolyphosphate (TPP) crosslinked chitosan (CH)-based fibrous matrices have potential as bioactive scaffolds for bone tissue engineering. This study describes mechanical, biomineralization, and in vitro bone cell growth and differentiation properties of CH-TPP (chitosan-tripolyphosphate) fibrous scaffolds and compared with that of uncrosslinked CH one. The hydrated CH-TPP scaffolds were viscoe...
متن کاملSodium Tripolyphosphate (TPP) Crosslinked Chitosan Membranes and Application in Humic Acid Removal
Macroor micro-porous chitosan membranes have been utilized as adsorptive membrane for the removal of metal ions, organic macromolecules or bioseparation of protein mixtures. The removal or separation mechanism is not based on physical size retention but based on the high adsorption capability of chitosan to the target solutes. For this purpose, it is important that large macro or micro pores an...
متن کاملSensitive Voltammetric Detection of Indomethacin Using TiO2 Nanoparticle Modified Carbon Ionic Liquid Electrode
In this work, a TiO2 nanoparticle modified carbon ionic liquid electrode (CILE) was employed as a sensitive sensor for the investigation of the electrochemical behavior of indomethacin (IND). This nanocomposite sensor has been fabricated by incorporation of TiO2 nanoparticles and the ionic liquid 1-hexylpyridinium hexafluorophosphate (HPFP). The surface of the electrode was studied by scanning ...
متن کاملAnodic Stripping Voltammetric Determination of Nitrite Using Carbon Paste Electrode Modified with Chitosan
A simple method for anodic stripping voltammetric determination of nitrite using carbon paste electrode modified with biomolecular chitosan, is described. In this method, the electrode is activated electrochemically by scanning 5 replicates over the potential range from +500 to +1400 mV immersing in 0.5 M HCl solution. Following this step, the nitrite sample containing 0.1 M KCl is pre-concentr...
متن کاملSelective Isolation of Trypsin Inhibitor and Lectin from Soybean Whey by Chitosan/Tripolyphosphate/Genipin Co-Crosslinked Beads
Selective isolation of Kunitz trypsin inhibitor (KTI) and lectin from soybean whey solutions by different types of chitosan beads was investigated. The chitosan beads were co-crosslinked with tripolyphosphate/genipin in solutions at pH 5, 7 or 9 (CB5, CB7, CB9). The maximum adsorption ratios of chitosan beads to KTI and lectin were observed at pH 4.4 and 5.4, respectively; highly selective sepa...
