Korean researchers have developed a "nano satellite" technology making obtaining data on occurences within a single tiny cell more easy and effective.

The technology works in the same manner as a satellite in orbit that collects information.

A Sogang University team says the study is being jointly conducted with University of California-Berkeley professor Luke Lee. The team developed a technology that gathers visual and space information of chemicals such heavy metal and protein contained in human cells.

The visual detection of when, where and how much biologically important chemicals exist in our body is considered a key technology to unveil phenomena of organisms and chemicals, diagnose disease, and develop cures.

The study is in the online edition of Nature Nanotechnology magazine and the team has filed for a U.S. patent.
