FEATURES
Optofluidics Emerges from the Laboratory For centuries, the components in optical systems have been made from a variety of glasses and metals. More recently, however, they have been created from plastic and semiconductor materials. In other words, optical materials in general are solid in nature. Though prominent examples of fluid materials in optical systems exist (e.g., liquid crystals, dye lasers and liquid mirror telescopes), by...
Quantum Systems Directly Probed by Photons Microcavity systems that track and measure the quantum interactions that occur between light and matter have been devised by two research teams in California. Although cavity quantum...
Ultrafast Electron Microscopy Reveals Laser Control of Nanochannels Scientists are interested in optoelectronics applications, such as optical memory storage, and in molecular machines that mimic biological molecules, which usually exhibit precision superior to that...

TECH PULSE
SERS in a Capillary Could Aid Biochemical Sensing on the Lab-on-a-Chip Scale Raman spectroscopy is useful for applications where high-specificity biological or chemical sensing is required. Unfortunately, sensitive detection using Raman-based sensors has proved more difficult, especially at the scale of lab-on-a-chip devices, because analytes passing through microchannels provide Raman signals that are very small. However, exploiting the effects of surface-enhanced Raman...
