Hydrogel beads based on the carbohydrate biopolymers kappa-carrageenan and sodium alginate were newly prepared. Both classical and experimental design (Taguchi) methods were used to obtain the optimum conditions for the full-polysaccharide hydrogel preparation. The carrageenan-alginate (Caralgi) beads exhibited a surface morphology smoother than that of the one-polysaccharide network beads. Infrared spectroscopy and DSC/TGA thermal methods were used to study the chemical structure and thermal properties of the beads. The carrageenan parts appreciably enhanced thermostability of the networks. The fully carbohydrate-based hydrogel beads are expected to be biologically compatible and degradable. They are being considered as new carriers for drug loading and controlled delivery systems.

UI MeSH Term Description Entries
D007477 Ions An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.
D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
