New opt-electronic microscope having high resolution of smaller than 10 nanometers is under development for imaging of living biological specimens. It is built by combining the best features of optical-microscope and electromicroscopes to take the image of a biological specimen in living condition and with very high magnification provided by electron microscopes.

Nano Imaging Technique for Clarifying Biofunction

A laser light beam is radiated to the specimen. Electrons emitted from the photoelectric film surface according to the intensity of light penetrating through the specimen is magnified and focused to project the enlarged image on a display.

Scanning probe microscopes (SPM) and atomic force microscopes (AFM) have a function as a knife in nano-scale machining. They can process nano-scale machining. A laser manipulator has a function as tweezers for nano-scale objects. They can pick and handle ultra small objects. AFM Micromachine Tools

The developed device is a new integrated machine of new scanning probe microscope systems with machining and manipulator functions. The device is used for an inspection and processing machine for nano-sized objects. The great possibility of using the device is expected for many applications in industry and bio-fields.

New device is currently under development to detect extremely tiny metal substances that is not detected by conventional technology. The device is the SQUID (super-conducting quantum interference device) having extremely high sensitivity of 1 billionth of the magnetism of earth.

This high sensitivity, for example, allows detecting tiny metallic contaminants in lithium batteries used in PC, cell phones, and cars that cause operating failures and sparks, etc. The technology of the high sensitive SQUID also helps reduce the size of NMR (Nuclear Magnetic Resonance) equipment.

3-4 Nanostructure Embedded Phosphor Particles and Ultra-High-Output UV Source
