An electrical engineer has developed a novel cancer cell detection method that will improve early diagnosis through a tool that tracks cellular behavior in real time using nanotextured walls that mimic layers of body tissue.
The semiconductor, made of the elements tin and oxygen, or tin monoxide, is a layer of 2D material only one atom thick, allowing electrical charges to move through it much faster than conventional 3D materials such as silicon.
While working to improve a tool that measures the pushes and pulls sensed by proteins in living cells, biophysicists at Johns Hopkins say they've discovered one reason spiders' silk is so elastic: Pieces of the silk's protein threads act like supersprings, stretching to five times their initial length.
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, scientists have successfully combined two different ultrathin semiconductors - each just one layer of atoms thick - to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics.
A new interdisciplinary study on the production of crystals can pave the way for faster drug discovery and delivery, and has several applications in the pharmaceutical, material sciences and biotechnology industry.
After more than half a decade of speculation, fabrication, modeling and testing, an international team of researchers have confirmed that their process for making carbon films and micro-supercapacitors will allow microchips and their power sources to become one and the same.
