Scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image of the faint electric fields generated by the rhythmic firing of the heart's muscle cells.
In this episode of the “Nano Matters” podcast, Heather Clark, Professor of Bioengineering and Chemistry at Northeastern University, describes her work on developing nanosensors to continuously measure biomarkers in the body.
Researchers have developed a blueprint for designing new materials using difficult combinations of nanocrystals. The work could lead to improvements in nanocrystals already used in displays, medical imaging, and diagnostics.
Engineers have discovered a new way of generating electricity using tiny particles that can create a current simply by interacting with liquid surrounding them. The particles are made of high-surface-area single-walled carbon nanotube networks.
Engineers have developed a technology that improves the resolution of an ordinary light microscope. The technology consists of a slide coated with a light-shrinking material made up of nanometers-thin alternating layers of silver and silica glass.
Researchers have developed a new technique using chemically sensitive soft X-rays that offers a simpler way of gaining insight into nanocarriers that either deliver therapeutic drugs in the body or clean up the environment.
Researchers have built an electron microscope pixel array detector that will enable them to locate individual atoms in all three dimensions. This scientific advance could be helpful in imaging semiconductors, catalysts, and quantum materials.
