Notes:
A polyelectrolyte complex (PEC) composed of chitosan (CS) and phosphorylated chitosan(PCS) was used to encapsulate a calcium phosphate by a biomimetic method. An acidic CS (polycation)solution containing calcium and phosphate ions (Ca2+: 6mM, Ca/P = 1.67) was added into PCS(polyanion) solution leading to the formation of a polyelectrolyte complex (PEC) with nanoscopiccarbonate-containing, low-crystallinity hydroxyapatite (HA) distributed evenly in the fibrils of the PECby controlled crystal growth. The resulting composite material, PEC-HA, has a complicated, hierarchicalporous structure that is expected to have high bio-compatibity and that may be of use as a carrier forcontrolled-release therapetic agents
