Caltech Scientists Power Reusable DNA Circuits With Heat to Enable Scalable Molecular Computing
Caltech scientists have created a fully reusable enzyme-free DNA computing system—unlocking new possibilities for autonomous ...
Computers come in many forms, depending on your definition. We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistors. However, there are ...
DNA-based nanotechnology has been around for more than 30 years, but it really took off in 2006, when DNA origami was featured on the cover of Nature. This form of origami, the folding of DNA into 2D ...
Scientists have announced that they have built and tested a new biomaterial-based delivery system -- known as a hydrogel -- that will encase a desired cargo and dissolve to release its freight only ...
