Is There a Platform for Artificial Cells?

i think this persistence problem that, while i find it interesting from a more, let's say, intellectual perspective on what is life, has very practical implications as well. I mean, there are lots of diseases nero neuro degenerative diseases like parkinson's disease where essentially your neuro transmitters like dopomine are not being produced as you get older. And if you built artificial cells that can sense the concentration s of dopemine, for example, and then synthesize more dopamin whenever the levels get too low, that sounds like a fantastic therapy. You could have artificial cells that are targeted to different parts of the body. Again, there's a lot of work to get there
