CSIRO scientist discovers natural "invisible" gold
Nanoparticles of gold too small to be seen with the naked eye have been created in laboratories, but up until now, have never been seen in nature.

Argonne research unveiling the secrets of nanoparticle haloing
A glass of milk, a gallon of paint and a bottle of salad dressing all look to the naked eye like liquids. But when viewed under a microscope these everyday liquids, called "colloids," actually contain small globules or particles that stay suspended in solution.

Brown Chemists Create Cancer-Detecting Nanoparticles
A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging (MRI). The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells. Once they bind, the particles emit stronger signals that MRI scans can detect.

Nanoworms Target Tumors
By linking strings of spherical iron oxide nanoparticles and coating the resulting construct with a biocompatible polymer, a multi-institutional research team has created “nanoworms” that can better target tumors and produce stronger magnetic resonance imaging (MRI) signals than their component nanoparticles.

Environmental Fate of Nanoparticles Depends on Water Carrying Them
The fate of carbon-based nanoparticles spilled into groundwater – and the ability of municipal filtration systems to remove the nanoparticles from drinking water – depend on subtle differences in the solution properties of the water carrying the particles, a new study has found.
