Researchers at the National Institute of Standards and Technology (www.nist.gov) have developed a new method to produce uniform, self-assembled nanocells for drug therapies, such as chemotherapy, in which dosage depends critically on the size of the nanocells. The new method uses micrometer-size channels etched into a device to produce self-assembled liposomes—a type of artificial nanocell—of specific sizes from 100 to 240 nm. A stream of lipids dissolved in alcohol is directed at an intersection of two channels while a water-based liquid containing medicines or other substances is sent toward the lipid stream from two opposing directions. Self-assembled nanocells are formed when the lipids surround the water rather than mixing with it.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
