چکیده انگلیسی
The self-assembly of rod-coil carboxymethyl konjac glucomannan-graft-poly(ethylene glycol) (CKGM-g-PEG) and α-cyclodextrin (α-CD) complexes were investigated and used as encapsulating hollow nanospheres for the enzyme glucose oxidase (GOX) in aqueous solution. These hollow nanospheres exhibited “cell-like” semi-permeability allowing enzyme substrates to pass through the surface while restricting the encapsulated enzyme (i.e. GOX) to the interior. Encapsulated GOX exhibited higher thermostability, optimal enzymatic activity over a wider pH range and improved storage stability in comparison to free un-encapsulated GOX. In addition, these CKGM-g-PEG/α-CD hollow nanospheres showed in vitro biocompatibility when exposed to L929 cells when tested using MTT viability assay. These studies suggested that self-assembly of CKGM-g-PEG and α-CD to form stable nanospheres may be an effective method for enzyme encapsulation with numerous biomedical applications.
