Yes, I think so. As others pointed out earlier, portable devices with immobilized reagents like pregnancy tests or glucose monitors already show the concept is (in principle) feasible; and there's been a lot of recent work dedicated to miniaturizing and integrating all steps of critical assays, including even the most elaborate ones [1]. It's pretty impressive stuff, so I expect a breakthrough anytime soon.

I definitely agree though it's a commendably well-thought-out project in itself, especially for the usual techno-bubbly standards of Silicon Valley hackatons of late.
