Researchers at Cornell University have developed a biological enzyme that functions like a tiny motor. Their program pushes the field of molecular engineering to a new level and raises hope for the role of bio-engineered sensory devices in preventing and combating human disease. The article continues an editorial series in the magazine focusing on the emerging field of nanotechnology.
Nanotechnology involves the creation of materials and devices at the atomic and molecular level.
The device developed at Cornell uses a chemical reaction to turn propellers. The propellers enable motion and, according to a video depiction, attract and emit tiny particles. While the researchers have every reason to be encouraged about their breakthrough, much experimentation and developmental work remain to create a device of practical value in the area of human health. The next step, according to Carlo Montemagno, Ph.D., a member of the research team at Cornell, is to determine specific force characteristics, fueling schemes, and active control of the tiny motor.
