全新“液体活检”芯片可以通过一滴血检测出转移性癌症

伍斯特理工学院的工程师们研究出一种全新的芯片,只需要用癌症患者体内的一滴血就可以检测出确定转移性癌细胞。

这一消息的惊人之处就在于其使用简单的方法带来了科技的又一飞跃。

根据《科学新闻日报》登载的所示,比起现有使用微流体诱捕癌细胞,这一全新的技术更加有效。

伍斯特理工学院的的研究小组成员解释说,这一设备就好像一口小井,井底的碳纳米管上附着着抗体,癌细胞来到井底,根据表面标记选择性的连接在抗体上,接着他们制作了名为“外来体”的细微小结构,这就是他们捕捉癌细胞的方法。

《纳米科技》中详尽介绍了“液体活检”的报告,这一全新科技将成为最简单的实验室实验,可以帮助检测出癌症转移的早期阶段,使医生更快更准确的进行治疗。

众所周知,癌细胞会通过一个器官转移到其他器官,转移的过程都是通过血液进行的,然而不同的癌症转移的器官也不尽相同。

比如,乳腺癌更容易转移到肺部,大脑或骨头中,如果可以早期判断出癌细胞转移的方向,那么再进一步恶化之前就可以采取措施。

目前存在的问题是,一小部分癌细胞漂浮在无数的红细胞和白细胞之间。不过,研究小组成员肯定了他们技术的高精准度。
