Nanoscale Measurement System
Background
 Construction of hybrid bio-nanosystems relies on measuring
and optimizing forces and displacements at the molecular level.
 The measurement of the forces and displacements involved when attaching
biological material to inorganic material or micro electro mechanical
systems (MEMS) is becoming an increasing import design capability.
Problem
 Conventional force transducers (e.g. load sensors) have been the choice
for the measurement of forces however these sensors do not have the
required sensitivity.
 Conventional force microscopy relies on cantilever torsional modes for
measuring forces along the surface plane, implying in poor
visualization and sensitivity.
 Optical tweezers have been the choice for the measurement of forces
produced by single molecules however this techniques has limited force
range (pN).
Markets
 Force and displacement characterization tools for the
nanotechnology market.
Nanoscale Measurement System
Solution
 Prototype has been fabricated that can detect forces of ~ 0.2 nN and a corresponding
displacement of ~ 40 nm.
 The prototype incorporates a novel illumination system that permits excellent
visualization of biological material.
 The system design permits flexible handling of liquids.
 This system fills the gap between existing tools for measuring forces associated with
biological elements and purely atomic measurement systems.
