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.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
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.
