This is a long way from any clinical use.

They aren't actually assessing how good it is as a tool to detect cancer, or monitor response to treatment: most of the paper is demonstrating that the device can analyse metabolic features of a lot of individual cells extracted from (mouse) blood at once - and it seems it can spot cancer cells that are in the blood. But being able to spot mouse cancer cells when you know there is a cancer is a long way from giving someone a blood test to spot cancer. This will be very dependent both on how sensitive and specific any test is, and how frequent the cancers are in the target populations (eg, is it the general population, or those with symptoms, or those at high-risk, or recurrent settings, etc).
