俄媒:黄金纳米微粒确能治癌 可直达病变源头

2017-09-17 14:06:39   中国青年网

俄媒称,俄罗斯和印度科学家发现,稳定的黄金纳米微粒进入血液时不会分解也不会黏合,将有效抗击肿瘤疾病。

俄罗斯《晨报》网站9月14日报道,在医学中金银微粒已被用于抗击各种恶性肿瘤,但这种微粒至今仍表现出相对不稳定性。进入血液时微粒相互黏合,导致血管堵塞,这些微粒也就无法到达病变部位。《韩国化学学会会刊》上发表的文章称,现在该问题成功获得解决。

莫斯科国立钢铁合金学院院长阿列夫京娜·切尔尼科娃介绍说:“我院科学家与印度同行联合制取出十分稳定的黄金纳米微粒,这种微粒注入血液时不再会发生聚合。”

微粒合成物呈多角星形状。正是这一形状令其在血管中不会黏合,可直达病变源头。黄金磁性纳米微粒将通过直接注入肿瘤的方式进入机体。在激光热疗法的作用下,这些微粒在肿瘤区域可产生有治疗效果的热效应,这将杀死癌细胞。

科学家认为,该方法还可有效诊断早期癌症并精确杀死病变细胞。
