  • 摘要:为了开发一种优异的用于光热治疗和光学相干层析成像的金纳米星诊疗剂,对金纳米星的制备、光热特性以及光热治疗和光学相干层析成像中的应用进行研究。利用尖端结构增强金纳米材料的局域表面等离子体共振特性,通过种子介导法制备了多枝化的金纳米星,多尖端的结构使其具有明显的光热效果,并探究了其作为光热治疗的诊疗剂和光学相干层析成像造影剂的效果。实验结果表明:多枝化的金纳米星诊疗剂相比于金纳米粒子具有较高的光热转换效率,达到42%;具有较好的生物兼容性,在100 μg/mL浓度下,人乳腺癌细胞存活率为82%;而且具有较好的癌细胞光热治疗效果,在100 μg/mL浓度下,经 照射后,人乳腺癌细胞被有效杀死,其存活率降至37%;同时,金纳米星诊疗剂还具有较好的光学相干层析成像造影效果,可显著提高信号强度和造影深度。金纳米星诊疗剂既具有高效光热治疗能力,又具备优异光学相干层析成像造影成像能力,是一种非常有前景的多功能诊疗剂。
