Nanoengineers have developed new and improved probes, known as positive controls, that could make it easier to validate rapid, point-of-care diagnostic tests for COVID-19 across the globe.
Scientists can use beams of electrons to study the properties of materials. For example, they can learn about the behavior of subatomic particles and molecular or atomic structure of a material. Shorter electron beams produce higher-resolution views of these properties.
Researchers constructed semiconductor heterojunctions that harvest sunlight, split water, and evolve hydrogen gas. The heterojunctional composites are composed of primary semiconductors, hetero-sites, and interfacial buffers.

A single nanoparticle can act like a laser at low power but still emit a sharp signal.
