Abstract
Layer-by-layer (LbL) alginate beads, which were prepared by multi-phase emulsion technique, had been fabricated via the ionic crosslinking between calcium ion (Ca2+) and the carboxylic group of alginate. The prepared beads were spherical, smooth-surfaced and non-aggregated. The SEM analysis displayed the LbL structure of the beads clearly. It had been demonstrated that the size of the beads was controllable and had a correlation with concentration of sodium alginate (SA) and CaCl2, ratio of water phase and oil phase (W/O), stirring speed, pH value of the water phase, viscosity of SA as well as the temperature for solidification. Stability studies showed that the beads degraded slowly in simulated gastric fluid and simulated intestinal fluid but degraded sharply when they were moved to simulated colonic fluid. Cytotoxicity study by MTT assay indicated that the prepared beads are slightly toxic. It is hoped that this kind of novel beads could be used in pharmaceutical area and cell culture area.
