Engineers at Stanford University (Stanford, CA, USA) have demonstrated a high-resolution endoscope that is as thin as a human hair with a resolution four times better than previous devices of similar design.
The so-called micro-endoscope is a significant step forward in high-resolution, minimally invasive bio-imaging, and has potential applications in research and clinical practice.
The new endoscope was developed by a team under the direction of Joseph Kahn, professor of electrical engineering at the Stanford School of Engineering.
Their prototype can resolve objects about 2.5 microns in size, and a resolution of 0.3 microns is easily within reach. By comparison, today's high-resolution endoscopes can resolve objects only to about 10 microns.
A complete technical description of the design of the micro-endoscope has been published on the Stanford University Engineering web site here.
