Researchers at Oak Ridge National Laboratory, Oak Ridge, TN, US, have built a new type microscope that provides a "chemical lens" for viewing biological systems including cell membranes and biofilms.

With a silicone rubber "stick-on" sheet containing dozens of miniature, powerful lenses, engineers are one step closer to putting the capacity of a large laboratory into a micro-sized package. The ...

Validating samples is a time consuming and expensive process when trying to track down defects and reasons for semiconductor failures. Optical microscopes were used to examine samples after each ...

Medical engineers have developed a hand-held microscope that can differentiate cancerous cells from healthy ones much faster than pathology labs Dennis Wise/University of Washington Medical engineers ...

A pocket holographic slide enables the high-throughput screening of fluid samples by embedding micro-optics directly on a micro-channel to achieve off-axis interferometric imaging. This holographic ...
