Using a four-quadrant detector and an A/D to detect cantilever motion, the feedback circuit drives the DC signal to the surface potential, minimizing cantilever motion and resulting in a map of the ...

For the first time, single cellular machineries can be watched at work ... probe cell surface properties and to elucidate the molecular mechanisms of cell adhesion. Microfabricated cantilever ...

Understanding the dynamics and impacts of raindrops on plant leaves has implications that extend beyond botany.
