US Patent:
8448261, May 21, 2013
Filed:
Mar 17, 2010
Appl. No.:
12/726083
Inventors:
Ali Passian - Knoxville TN,
Thomas George Thundat - Knoxville TN,
Laurene Tetard - Knoxville TN,
Assignee:
University of Tennessee Research Foundation - Knoxville TN
UT-Battelle, LLC - Oak Ridge TN
International Classification:
G01Q 60/24
G01Q 60/58
US Classification:
850 37, 850 50
Abstract:
A method of analyzing a sample that includes applying a first set of energies at a first set of frequencies to a sample and applying, simultaneously with the applying the first set of energies, a second set of energies at a second set of frequencies, wherein the first set of energies and the second set of energies form a multi-mode coupling. The method further includes detecting an effect of the multi-mode coupling.

Microscale Fluid Transport Using Optically Controlled Marangoni Effect

US Patent:
2009002, Jan 22, 2009
Filed:
Jul 16, 2007
Appl. No.:
11/778162
Inventors:
Thomas G. Thundat - Knoxville TN,
Ali Passian - Knoxville TN,
Rubye H. Farahi - Oak Ridge TN,
Assignee:
UT-BATTELLE, LLC - Oak Ridge TN
International Classification:
G01N 27/26
US Classification:
204450, 204600
Abstract:
Low energy light illumination and either a doped semiconductor surface or a surface-plasmon supporting surface are used in combination for manipulating a fluid on the surface in the absence of any applied electric fields or flow channels. Precise control of fluid flow is achieved by applying focused or tightly collimated low energy light to the surface-fluid interface. In the first embodiment, with an appropriate dopant level in the semiconductor substrate, optically excited charge carriers are made to move to the surface when illuminated. In a second embodiment, with a thin-film noble metal surface on a dispersive substrate, optically excited surface plasmons are created for fluid manipulation. This electrode-less optical control of the Marangoni effect provides re-configurable manipulations of fluid flow, thereby paving the way for reprogrammable microfluidic devices.

Scanning Probe Microscopy With Spectroscopic Molecular Recognition

US Patent:
2011023, Sep 22, 2011
Filed:
Mar 17, 2010
Appl. No.:
12/726118
Inventors:
Ali Passian - Knoxville TN,
Laurene Tetard - Knoxville TN,
Thomas George Thundat - Knoxville TN,
Brian Henry Davison - Knoxville TN,
Martin Keller - Knoxville TN,
International Classification:
G01Q 60/00
G01N 29/04
US Classification:
850 21, 73584
Abstract:
A method for determining chemical characteristics of a sample, the method including directly applying a first acoustic wave at a first frequency to a probe and applying, independent of the directly applying the first acoustic wave, a second acoustic wave at a second frequency to the sample, wherein the first frequency is different than the second frequency and the first acoustic wave and the second acoustic wave are simultaneously applied to the probe and the sample, respectively, and form a coupling. The method further including applying electromagnetic energy to the sample, wherein the electromagnetic energy is absorbed by the sample causing a change in phase of the second acoustic wave. The method further including detecting an effect of the coupling and determining a spectrum of the sample based on the detecting.
