Accession number: 20140117165968 Title: The research on the base material of polyacrylamide/chitosan hydrogel Authors: Wu, Gui-Sheng1; Ye, Zhi-Yi1 Author affiliation: 1 College of Bioengineering, Chongqing University, Chongqing 400044, China Corresponding author: Ye, Z.-Y. Source title: Gongneng Cailiao/Journal of Functional Materials Abbreviated source title: Gongneng Cailiao Volume: 44 Issue: 20 Issue date: October 30, 2013 Publication year: 2013 Pages: 2949-2953 Language: Chinese ISSN: 10019731 CODEN: GOCAEA Document type: Journal article (JA) Publisher: Journal of Functional Materials, P.O. Box 1512, Chongqing, 630700, China Abstract: A new type of hardness variable biological substrate material was prepared. Experiments of infrared spectroscopy, water absorption of weighing, the rotational rheometer, and MTT were conducted to measure the structure, swell ability, elastic modulus and cytotoxicity of polyacrylamide/chitosan hydrogel HepG2 cells were inoculated into the mixed hydrogel base material of polyacrylamide/chitosan, and the morphology of the cells grown on the materials was observed after 24h. The hardness of the different formulation of polyacrylamide/chitosan hydrogel had obvious gradient differences and good biocompatibility. This new type of the biological substrate material could contribute to the research of cell mechanics. Number of references: 23 Main heading: Biological materials Controlled terms: Biocompatibility - Chitosan - Hardness - Hydrogels - Infrared spectroscopy Uncontrolled terms: Base material - Biological substrates - Cell mechanics - Hep-g2 cells - MTT assays - Rotational rheometer - Structure , swell Classification code: 951 Materials Science - 804.1 Organic Compounds - 804 Chemical Products Generally - 741.1 Light/Optics - 461.9.1 Immunology - 461.2 Biological Materials and Tissue Engineering - 421 Strength of Building Materials; Mechanical Properties DOI: 10.3969/j.issn.1001-9731.2013.20.010 Database: Compendex Compilation and indexing terms, © 2014 Elsevier Inc. |
