Engineers open the door to a large new library of tiny nanoparticles

Using conventional bimetallic synthesis methods, only easily miscible metals (shown in green) can mix with Cu, while others (shown in red) form phase-segregated structures (such as core-shell). In contrast, Cu and other metals can be kinetically enclosed in homogeneously mixed nanoparticles via the non-equilibrium synthesis, regardless of their thermodynamic miscibility.

Electron-behaving nanoparticles shatter the current understanding of matter

Credit: CC0 Public Domain It is not an electron. But it really does. Northwestern University researchers have made a strange and startling discovery that nanoparticles made with DNA in colloidal crystals – when they are extremely small – behave like electrons. Not only has this knowledge turned the current accepted concept of matter upside down, it has also opened the …

Tiny robots powered by magnetic fields could help nanoparticles deliver their drug targets

A vision of improved transport of nanomedicine into tumor tissue. Picture credits: Sonia Monti MIT engineers have developed tiny robots that can help deliver nanoparticles from the bloodstream to a tumor or other disease site for drug delivery. Like the craft of "Fantastic Voyage" – a science fiction movie from the 1960s, in which a submarine crew shrinks in size …

Scientists Give Mice a "Night Vision" Science Using Nanoparticle Injections | Night vision | Mice | Nanoparticles | injections

Scientists say they successfully gave mice "night vision" so they can see infrared light with minimal side effects. Research could lead to advances in human infrared vision technologies, including potential applications in civilian encryption and security and military deployments, scientists said. According to the study published in the journal Cell, a single injection of nanoparticles in the eyes of the …

A shot of nanoparticles leaves mice in the dark

An image of nanoparticles leaves mice in the dark When injected into the eye, the particles change the infrared light to allow for night vision. How it works: The nanoparticles adhere to the retinal cells of the eye, which convert light into electrical signals. They transformed infrared light that mice can not see into green light, as they can. Tests: …
