Measuring the mass of molecules on the nano-scale

Working with a device that slightly resembles a microscopically tiny tuning fork, researchers have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error — potentially enabling the weighing of individual molecules in liquid environments.

Ultrafast heat conduction can manipulate nanoscale magnets

Researchers have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal energy, in contrast to the conventional application of magnetic fields, providing a new, and highly desirable way to manipulate magnetization at the nanoscale.

Filming the film: Scientists observe photographic exposure live at the nanoscale

Photoinduced chemical reactions are responsible for many fundamental processes and technologies, from energy conversion in nature to micro fabrication by photo-lithography. Scientists have now monitored the chemical processes during a photographic exposure at the level of individual nanoscale grains in real-time.

Nanoscale building blocks and DNA ‘glue’ help shape 3D architectures

Scientists devised a new way of assembling ordered crystals made of nanoparticles. In this process, nanoparticles in the shape of cubes, octahedrons, and spheres coordinate with each other to build structures. The shapes are bound together by complementary DNA molecules on each type of particle.
