Programmable Micro-Carriers

Authors: George Rajna

In the life sciences, researchers are working to inject drugs and other molecules using tiny transport vehicles. Researchers at the Saarland University and the University of Barcelona have shown in a model system that small emulsion droplets can be used as smart carriers. [34] A team of scientists working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has confirmed a special property known as "chirality—which potentially could be exploited to transmit and store data in a new way—in nanometers-thick samples of multilayer materials that have a disordered structure. [33] By exploiting a hidden symmetry in the material, their results support a theory first proposed 20 years ago. [32] Scientists working in the field of organic chemistry create and study new molecules using magnetic resonance. [31] A team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has demonstrated the possibility to induce and control a magnetic response in a nonmagnetic layer material though selective excitation of specific vibration of the material. [30] A new material created by Oregon State University researchers is a key step toward the next generation of supercomputers. [29] Magnetic materials that form helical structures—coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule—occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors—sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields. [27] At Carnegie Mellon University, Materials Science and Engineering Professor Mike McHenry and his research group are developing metal amorphous nanocomposite materials (MANC), or magnetic materials whose nanocrystals have been grown out of an amorphous matrix to create a two phase magnetic material that exploits both the attractive magnetic inductions of the nanocrystals and the large electrical resistance of a metallic glass.
