Imagine a hand-held environmental sensor that can instantly test water for lead, E. coli, and pesticides all at the same time, or a biosensor that can perform a complete blood workup from just a single drop. That's the promise of nanoscale plasmonic interferometry, a technique that combines nanotechnology with plasmonics - the interaction between electrons in a metal and light.
In what may provide a potential path to processing information in a quantum computer, researchers have switched an intrinsic property of electrons from an excited state to a relaxed state on demand using a device that served as a microwave 'tuning fork'.
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.
