Abstract
Conversion of Pomacea lineate shells into hydroxyapatite (HA) bioceramic materials was investigated by their in vitro treatment with phosphate solutions, at room temperature. Confocal Raman microscopy revealed that the conversion proceeds at distinct rates through the nacreous or periostracum sides of the shell. The conversion can be accelerated using powdered samples, yielding biocompatible materials of great interest in biomedicine.
摘要
研究了在室温下用磷酸盐溶液对福寿螺壳进行体外处理，将其转化为羟基磷灰石（HA）生物陶瓷材料。共焦拉曼显微镜显示，转化过程通过贝壳的珍珠层或角质层以不同的速率进行。使用粉末样品可以加速转化，得到生物相容性好的材料，在生物医学领域具有很大的应用前景。
