This exhaustive review of paper-based microfluidics technology has me thinking about how interesting the biosensing industry is becoming (and where investment opportunities lie). Also, though, it made me curious about laser-cutting microfluidic logic gates, which has led me to rediscover liquid computing, bubble logic, and the Center for Bits and Atoms.

I have a (poorly-informed) sense that people studying this space end up in exciting research about metamaterials and other exotic, quantum physics. I wish there was more hacking around with things an average person can understand, which can have educational merit and feels more likely to change the world at scale.

I posted this in August 2023 during week 2581.
