This is fascinating new technology, Ann. I would imagine one of the applications could be targeting chemotherapy to the cancer instead of having to broadcast it to healthy cells as well as cancerous cells.
Isn't this amazing? Targeted drug delivery is definitely one of the possible apps the researchers have in mind, and if that could be done for chemotherapy it would make a lot of people healthier and happier.
Thanks williamlweaver, glad you liked the article. Self-assembled devices is becoming quite an an active area of research. I have read Crichton's PREY: pretty scary stuff, in fact I found it his scariest so far because it's so believable, perhaps even inevitable. Thanks for the link to your swarms article--another area of research that's getting a lot of play, especially in robotics.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
