Calcium phosphate is the inorganic mineral of hard tissues such as bone and teeth. Due to their similarities to the natural bone, calcium phosphates are highly biocompatible and biodegradable materials that have found numerous applications in dental and orthopedic implants and bone tissue engineering. In the form of nanoparticles, calcium phosphate nanoparticles (CaP's) can also be used as effective delivery vehicles to transfer therapeutic agents such as nucleic acids, drugs, proteins and enzymes into tumor cells. In addition, facile preparation and functionalization of CaP's, together with their inherent properties such as pH-dependent solubility provide advantages in delivery and release of these bioactive agents using CaP's as nanocarriers. In this review, the challenges and achievements in the intracellular delivery of these agents to tumor cells are discussed. Also, the most important issues in the design and potential applications of CaP-based biominerals are addressed with more focus on their biodegradability in tumor microenvironment.

用于癌症治疗的可生物降解的磷酸钙纳米颗粒。



磷酸钙是骨骼和牙齿等硬组织的无机矿物质。由于与天然骨相似,磷酸钙是高度生物相容性和可生物降解的材料,在牙科和骨科植入物以及骨组织工程中有着广泛的应用。以纳米颗粒的形式,磷酸钙纳米颗粒(CaP's)也可以用作有效的递送载体,将核酸、药物、蛋白质和酶等治疗剂转移到肿瘤细胞中。此外,CaP 的简便制备和功能化及其固有特性(例如 pH 依赖性溶解度)为使用 CaP 作为纳米载体递送和释放这些生物活性剂提供了优势。在这篇综述中,讨论了将这些药物细胞内递送至肿瘤细胞的挑战和成就。此外,基于 CaP 的生物矿物质的设计和潜在应用中最重要的问题也得到了解决,更多地关注其在肿瘤微环境中的生物降解性。
