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.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
