Study Notes
Abalone Shells
- Abalone is a large marine gastropod mollusk found in cold waters of New Zealand, Australia, South Africa, Japan, and the west coast of North America.
- The abalone shell is flat and spiral-shaped with several small holes around the edges, and its interior has an iridescent mother of pearl (nacre) pattern.
- Lianjiang County, Fujian Province, China is home to abalone and produces over 10,000 tons of abalone annually.
- Abalone shells are mainly composed of approximately 95% calcium carbonate and a small amount of proteoglycan and other organic matter.
- The inorganic phase of the abalone shell consists of stable calcite and metastable aragonite.
Abalone Shells as Biomimetic Molecule
- Hydroxyapatite (HAP) prepared from marine materials has excellent biocompatibility and bioactivity in vivo and in vitro.
- Spherical HAP is widely used in biomedical applications due to its large surface area, adsorption capacity, and other characteristics.
- Carbonate-substituted HAP (bio-HAP) has better bioactivity and biocompatibility due to its similarity to human bone and teeth components.
Previous Work
- The abalone industry has brought environmental concerns due to their inedible shells.
- Porous microspheres of carbonate-substituted hydroxyapatite (HAP) were prepared by a hydrothermal method using abalone shells.
- The porous HAP microspheres were approximately 6 μm in size with a considerable specific surface area and average pore size, ensuring excellent drug-handling capacity.
- The pH responsiveness of the drug release system was favorable for effective in vivo drug release in an acidic tumor microenvironment.
