Robotic Red Blood Cells




There's one nano-engineered device that cures type 1 diabetes. It's blood cell-sized. They put tens of thousands of these in the blood cell -- they tried this in rats -- it lets insulin out in a controlled fashion, and actually cures type 1 diabetes. What you're watching is a design of a robotic red blood cell, and it does bring up the issue that our biologyis actually very sub-optimal, even though it's remarkable in its intricacy. Once we understand its principles of operation, and the pace with which we are reverse-engineering biology is accelerating, we can actually design these things to be thousands of times more capable. An analysis of this respirocyte, designed by Rob Freitas, indicates if you replace 10 percent of your red blood cells with these robotic versions, you could do an Olympic sprint for 15 minutes without taking a breath. You could sit at the bottom of your pool for four hours --so, "Honey, I'm in the pool," will take on a whole new meaning. It will be interesting to see what we do in our Olympic trials. Presumably we'll ban them, but then we'll have the specter of teenagers in their high schools gyms routinely out-performing the Olympic athletes. Freitas has a design for a robotic white blood cell. These are 2020-circa scenarios, but they're not as futuristic as it may sound. There are four major conferences on building blood cell-sized devices; there are many experiments in animals. There's actually one going into human trial, so this is feasible technology.


Also here he is on Big Think making similar predictions.
