11. Accurate Noncontact Calibration of Colloidal Probe Sensitivities in Atomic Force Microscopy
Published: 6/15/2009
Authors: Koo-Hyun Chung, Gordon Allan Shaw, Jon Robert Pratt
Abstract: The absolute force sensitivities of colloidal probes comprised of atomic force microscope, or AFM, cantilevers with microspheres attached to their distal ends are measured. The force sensitivities are calibrated through reference to accurate electros ...

12. Methods for transferring the SI unit of force from millinewtons to piconewtons
Published: 6/1/2009
Authors: Gordon Allan Shaw, Koo-Hyun Chung, Douglas T Smith, Jon Robert Pratt
Abstract: The establishment of standards for small force measurement requires a link to an absolute measurement of force traceable to the international system of units (SI). To this end, a host of different means are being employed by the NIST small force meas ...

13. Contactless Differential Conductivity Detection
Published: 10/12/2008
Authors: Gordon Allan Shaw, David J Ross, Steven Earl Fick, Wyatt N Vreeland
Abstract: We propose a new technique, contactless differential conductivity detection (CDCD,) to improve the detection limit of contactless conductivity detection for capillary and microchannel electrophoresis. By exploiting a 3-electrode differential configu ...

14. SI traceable calibration of an instrumented indentation sensor spring constant using electrostatic force
Published: 9/22/2008
Authors: Koo-Hyun Chung, Stefan Scholz, Gordon Allan Shaw, John A Kramar, Jon Robert Pratt
Abstract: We present a measurement scheme for creating reference electrostatic forces that are traceable to the International System of Units (SI). This scheme yields references forces suitable for calibrating the force sensitivity of instrumented indentation ...

15. A New Microdevice for SI-Traceable Forces in Atomic Force Microscopy
Published: 6/2/2008
Authors: Gregory W Vogl, Jason John Gorman, Gordon Allan Shaw, Jon Robert Pratt
Abstract: A new self-excited micro-oscillator is proposed as a velocity standard for dissemination of nanoNewton-level forces that are traceable to the International System of Units (SI). The microfabricated oscillator is top-coated with magnetic thin films an ...

16. Reducing Thermal Noise in Molecular Force Spectroscopy
Published: 6/2/2008
Author: Gordon Allan Shaw
Abstract: Molecular force spectroscopy is the practice of testing the mechanical properties of single molecules.  The precision determination of these properties requires an instrument capable of piconewton-level force measurement.  The atomic force ...

19. Spring constant calibration of AFM cantilevers with a piezosensor transfer standard
Published: 9/24/2007
Authors: Eric Langlois, Gordon Allan Shaw, John A Kramar, Jon Robert Pratt, Donna C. Hurley
Abstract: We describe a method to calibrate the spring constants of cantilevers for atomic force microscopy (AFM). The method makes use of a piezosensor comprised of a piezoresistive cantilever and  accompanying electronics. The piezosensor was calibrated ...

20. Direct  Electrostatic Calibration of Hybrid Sensors for Small Force Measurement
Published: 6/4/2007
Authors: Koo-Hyun Chung, Gordon Allan Shaw, Jon Robert Pratt
Abstract: The measurement of forces from piconewtons to millinewtons is an area of interest from both an applied and pure research standpoint, however creating a link between small forces and the International System of Units (SI) has been difficult. In this w ...
