金纳米粒子(GNP)在生物医学领域的应用已经显示出巨大的潜力。然而,目前没有临床批准的可注射GNP制剂。相反,金盐在临床上使用了近世纪。此外,有证据表明在用金盐治疗的患者中GNP形成(即,金黄色葡萄球菌病)。最近在人细胞和鼠模型中评估这种现象的报道表明,使用金离子原位形成治疗诊断GNP可以大大改善致密生物组织内的递送,增加细胞内金摄取的效率和癌细胞内GNP形成的特异性。这些属性与金盐的安全临床应用相结合,使该工艺成为临床转化的可行策略。在这里,第一个总结目前的知识有关的GNP在哺乳动物细胞中的生物矿化提供了沿着的重要评估潜在的生物医学应用这一新兴领域。哺乳动物细胞可以从金盐的离子合成纳米颗粒。金盐药物已经在临床上应用了近世纪,有证据表明这些患者体内形成了纳米颗粒。然而,这些金药物的主流使用大大早于金颗粒的流行研究。在这里,一个新出现的领域,其中生物医学相关的金颗粒原位制备。
Gold nanoparticles (GNPs) have shown considerable potential in a vast number of biomedical applications. However, currently there are no clinically approved injectable GNP formulations. Conversely, gold salts have been used in the clinic for nearly a century. Further, there is evidence of GNP formation in patients treated with gold salts (i.e., chrysiasis). Recent reports evaluating this phenomenon in human cells and in murine models indicate that the use of gold ions for in situ formation of theranostic GNPs could greatly improve the delivery within dense biological tissues, increase efficiency of intracellular gold uptake, and specificity of GNP formation within cancer cells. These attributes in combination with safe clinical application of gold salts make this process a viable strategy for clinical translation. Here, the first summary of the current knowledge related to GNP biomineralization in mammalian cells is provided along with critical assessment of potential biomedical applications of this newly emergent field. Mammalian cells can synthesize nanoparticles from ions from gold salts. Gold salt drugs have been clinically applied for nearly a century, with evidence of nanoparticle formation within those patients. However, the mainstream use of these gold drugs considerably predates popular study of gold particles. Here a newly emergent field is summarized, wherein biomedically relevant gold particles are prepared in situ.
