Designed Molecules Trap Cancer Cells in Deadly Cages

Chemists have designed a carbohydrate-based molecule that can surround and strangle bone cancer cells by self-assembling into a tangled web of nanofibers. (Learn More >>)

Nanowire Clothing Could Keep People Warm

Scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes. (Learn More >>)

Fast, Accurate New Nanoparticle-Based Sensor System for Screening Cancer Drugs

Using an engineered gold nanoparticle and three fluorescent proteins provides "a three-channel sensor that can be trained to detect subtle changes in cell surface properties." (Learn More >>)

NASA Experiments with Self-Assembly Techniques on the International Space Station

The Structure of Paramagnetic Aggregates from Colloidal Emulsions (InSPACE) experiments explored nanoparticles suspended in magnetorheolocial fluids, a type of smart fluid that tends to self-assemble into shapes in the presence of a magnetic field. (Learn More >>)

Technique Simultaneously Determines Nanomaterials’ Chemical Makeup

Researchers from DOE's Argonne National Laboratory & Ohio Univ. have devised a powerful technique that simultaneously resolves the chemical characterization and topography of nanoscale materials down to the height of a single atom. (Learn More >>)

Bullet-Proof Armour and Hydrogen Sieve Add to Graphene’s Promise

One-atom-thick material blocks 'bullet' strikes but allows protons to pass through. (Learn More >>)

Nanoparticle Detects the Deadliest Cancer Cells in Blood

The nanoparticles—dubbed nanoflares—attach themselves to individual cancer cells in a blood sample and then glow, allowing cancerous cells to be detected and sorted with the help of a laser. (Learn More >>)

Nanomaterial Converts 90% of Captured Light into Heat

This work was funded by the U.S. Department of Energy's SunShot program. (Learn More >>)

Crystallizing the DNA Nanotechnology Dream

For the last 20 years, scientists have tried to design large DNA crystals with precisely prescribed depth and complex features—a design quest just fulfilled by a team at Harvard's Wyss Institute for Biologically Inspired Engineering. (Learn More >>)

Optimal Particle Size for Anticancer Nanomedicines Discovered

Researchers evaluated the size-dependent biological profiles of three monodisperse drug-silica nanoconjugates to determine the optimum particle size for tissue penetration and tumor inhibition. (Learn More >>)
