system (MEMS) that can be easily machined and
mass-produced via the same techniques used to make computer chips. The
ability to detect extremely small displacements make nanocantilever beams an
ideal device for detecting extremely small forces, stresses and masses.
Nanocantilevers coated with antibodies, for example, will bend from the mass
added when substrate
binds to its antibody, providing a detector capable of sensing the presence
of single molecules
of clinical importance.
