Three-dimensional polymeric microtiles for fluidic self-assembly

The microtiles are fabricated out of the superposition of two structural SU-8 layers featuring chiral copies of the same centro-symmetric pattern. They can coordinate laterally in water independently of their vertical orientation to form close-packed square lattice clusters.

Rotational X-ray tracking uncovers hidden motion at the nanoscale

An international team of scientists has developed a new technique called rotational X-ray tracking (RXT). The researchers were successful in demonstrating the power of the new technique by using it to study small crystalline particles immobilized by the fact they form a colloidal gel under certain conditions.

New nanotechnology method sneaks drugs into cancer cells before triggering release

Biomedical engineering researchers have developed a nanotechnology anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are inside a cancer cell, where they then combine to destroy the cell.

A simple doping method improves properties of carbon nanotubes

Researchers have developed a simple method for controlling the 'doping' of carbon nanotubes (CNTs), a chemical process that optimizes the tubes? properties. The method could improve the utility of doped CNTs in a number of nanotechnologies and flexible electronics, including CNT-silicon hybrid solar energy cells.
