Google 一直走在高精尖技术的前沿,不少计划项目让人目瞪口呆,比如人工智能、海底电缆、高空基站、未来城市……Google 今后还能玩出什么科幻电影级别的花样,还真是让人充满好奇。

最近,华尔街日报又报道了 Google 研发的一项新技术:血液机器人。机器人能达到纳米级别,进入人体血液,时刻侦测人体状况。

在电影《零度空间》中,男主角是微缩飞行器的驾驶员,这台飞行器比细胞还要小,于是,男主角就在人体之中来了一场奇幻之旅。

而 Google 的纳米机器人就是类似的“旅行器”。Google 说,机器人的大小可以小于千分之一个红细胞的宽度。当它进入人体后,会追踪并吸附到细胞、蛋白质或人体其他分子上。此外,Google 还会为使用者配备一款可穿戴设备,上面的磁铁能够吸引机器人并计数,作为一个中枢管理设备。

纳米机器人的目的,是来提供一种早期监测疾病的医疗方式,对癌症等病患来说,具有很高的实用性。

“以往,你需要去医院才能做的检查,都可以用这个系统来完成,这就是我们的目标。” Google X 实验室生命科学小组的负责人 Andrew Conrad 说。

但是,这项技术同 Google 诸多天马行空的计划一样,面临很多现实难题。机器人怎样制造、一位病人需要多少这些问题都需要进一步研究。此外,更重要的一点是电池,如此小的机器人要有足够的续航,同时又不能频繁的充电。

除了技术上,纳米机器人也有一些社会问题,比如社会接受度,以及行业监管,还涉及个人隐私的争议。

即便如此,Google 的纳米机器人技术如果变现,仍然有着很大应用空间,它将极大的提高医疗检测的精确度。

“我们需要知道人体血液中,带病分子的健康水平。但是现在,我们无法知道。”Andrew Conrad 说。
