据澳大利亚广播公司日前报道,澳大利亚科研团队发明了一种可分离血液中癌细胞的生物芯片,能甄别出血液中的癌细胞并将其移除。该技术可大幅降低癌症治疗费用,有望延长患者生命。

澳大利亚新南威尔士大学的一个科研团队研发的这种生物芯片,在一个名为“癌症透析”的设备中过滤血液,甄别并移除癌细胞。该团队研发这种芯片的初衷,是想寻找一种较便宜且痛苦较少的癌症诊断方法。

团队负责人马吉德·瓦尔基阿尼博士称,人类癌症中99%的癌症是实体瘤,而进入人体外周血(除骨髓之外的血液)循环的癌细胞会随着血液转移,扩散到身体其他部位。根据癌细胞比健康细胞大,代谢较旺盛的特点,医生将混有健康细胞和癌细胞的血液放入生物芯片中,在液体压力的影响下,较大的癌细胞和较小的健康细胞分别进入不同的出口,成功分离。

该芯片还能大幅降低与癌症相关的治疗成本。据了解,澳大利亚进行肿瘤检测的扫描费约700澳元(约合3229元人民币),而用这种芯片检测血液中癌细胞的成本仅为50到100澳元(约合230元至460元人民币)。

此外,该技术或能延长癌症患者的生命。有医生建议,如果能制作大型芯片,癌症患者的血液就如同接受肾透析一样得到“清洗”。将分离了癌细胞的血液重新输回患者体内,也避免了因输入他人血液造成的免疫反应。对于癌症早期患者,可通过这种技术降低癌症转移扩散的几率。

Sci Rep:开发超高速DNA分离技术 有望实现实时基因检测

日本名古屋大学研究人员日前宣布,他们开发出了只需数秒就能分离 DNA 的新技术,这让超高速解析 DNA 信息成为可能,有望实现即时基因检测。这一成果已发表在《科学报告》杂志上,该研究团队并为此申请了技术专利。DNA 是承载着生命信息的物质,在细胞内以双螺旋链的形式存在,对其进行分离、解析是一件非常繁琐耗时的工作。分离 DNA 需要根据 DNA 链的长短使用不同的材料,这使得现有的 DNA 分离、解
