LCDs get brighter with nano polarization recycler

LCDs (liquid crystal displays) provide a popular method for lighting screens on everything from computers and TVs to watches, clocks, cell phones and more. However, as scientists Sang Hoon Kim, Joo-Do Park and Ki-Dong Lee ...

Nanoscale magnetic imaging of ferritin in a single cell

In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...

Bright colors produced by laser heating

Most of the colors on today's paper and fabric are made using dyes or pigments. But colors can also be produced by modifying a material's surface at the nanoscale, causing the surface to reflect or scatter different frequencies ...

Solving mazes with single-molecule DNA navigators

The field of intelligent nanorobotics is based on the great promise of molecular devices with information processing capabilities. In a new study that supports the trend of DNA-based information carriers, scientists have ...
