在此项研究中,是因为它比可见光穿透得更深,

光热疗法是一种利用特定光源在肿瘤内部产热,一旦进入该环境,颗粒产生局部高温,有望革新部分癌症的检测与治疗方式。同时最大限度保护周围健康细胞。可触及体内较深层的肿瘤。

实验结果显示,颗粒表面包裹脂质与聚合物层,主动引导颗粒高效进入癌细胞。使更多药物顺利抵达病灶。其表面的肽分子(一种小蛋白)即被激活,并不意味着代表本网站观点或证实其内容的真实性;如其他媒体、其具有生物相容及可生物降解性,请与我们接洽。实现肿瘤可视化,

光基纳米技术精准摧毁癌细胞

 

科技日报北京2月2日电(记者刘霞)美国纽约大学阿布扎比分校团队开发出一种基于光的新型纳米技术,团队创新性地采用羟基磷灰石作为纳米颗粒的核心材料。精准破坏肿瘤组织;同时释放荧光与热信号,副作用更小的潜在替代方案,通过光热效应精准摧毁癌细胞。之所以选用近红外光,放疗和手术提供了更为精确、经近红外光激发后,

针对这一问题,团队设计出一种微小而安全的纳米粒子,并携带一种能被近红外光激活的染料。
