Nanoprobe to detect single cancer cell

Silicon nanotube-based electrical probes, as ultra-accurate signal recorders with subcellular resolution, may create many opportunities for fundamental biological research and biomedical applications. Here, this technology is used to electrically monitor cellular mechanosensing.

Researchers demonstrate electroluminescence from multilayer molybdenum disulfide

A new study is the first demonstration of electroluminescence from multilayer molybdenum disulfide, a discovery that could lead to a new class of materials for making LEDs.

Imaging glucose uptake activity inside single cells

Researchers have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance.

Researchers have developed a new method to capture the 3D structures of nanocrystals (w/video)

The novel imaging method will allow researchers to investigate the 3D structure of metallic nanoparticles for the first time.

Nanowires give 'solar fuel cell' efficiency a tenfold boost

A solar cell that produces fuel rather than electricity. Researchers today present a very promising prototype.

Bringing back the magic in metamaterials

A single drop of blood is teeming with microorganisms - imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a 'perfect lens'. The lens hasn't been created yet but it is a theoretical perfected optical lens made out of metamaterials, which are engineered to change the way the materials interact with light.

New method to test candidate material for organic solar cells

New research shows it is possible to test a candidate material quickly and directly, using off-the-shelf laser technology. The method bypasses the costly, time-consuming step of constructing a prototype solar cell for each material to be evaluated.

Imaging lipid rafts reveals some surprises

Raman microscopy of artificial monolayers suggests that lipids in cell membranes may have an unexpected distribution.
