Patent number: 7123764Abstract: An image processing method for use in analyzing image data of a cellular migration assay. The method includes defining a major axis within the image data that is perpendicular to an orientation of channels in the image data, determining an aggregate light intensity within the image data along the major axis, and identifying locations of channels within the image data from the projection.Type: GrantFiled: March 15, 2002Date of Patent: October 17, 2006Assignee: Surface Logix Inc.Inventors: Gregory L. Kirk, Matthew Brown, Emanuele Ostuni, Enoch Kim, Bernardo D. Aumond, Olivier Schueller, Paul Sweetnam, Brian Benoit

Patent number: 6921660Abstract: The present invention discloses a device for monitoring chemotaxis or chemoinvasion including a housing comprising: a support member and a top member, the top member mounted to the support member by being placed in substantially fluid-tight conformal contact with the support member. The support member and the top member are configured such that they together define a discrete chamber adapted to allow a monitoring of chemotaxis or chemoinvasion therein. The discrete chamber includes a first well region including at least one first well, the at least one first well configured to received a test agent therein; a second well region including at least one second well, the at least one second well configured to receive a sample comprising cells therein; and a channel region including at least one channel connecting the first well region and the second well region with one another. The second well region is preferably horizontally offset with respect to the first well region in a test orientation of the device.Type: GrantFiled: March 15, 2002Date of Patent: July 26, 2005Assignee: Surface Logix, Inc.Inventors: Gregory L. Kirk, Matthew Brown, Emanuele Ostuni, Enoch Kim, Bernardo D. Aumond, Olivier Schueller, Paul Sweetnam, Brian Benoit

Patent number: 6811968Abstract: The present invention discloses a method of monitoring chemotaxis or chemoinvasion comprising: providing a device for monitoring chemotaxis. The device includes a support member; a top member mounted to the support member by being placed in substantially fluid-tight, conformal contact with the support member. The support member and the top member are configured such that they together define a discrete assay chamber. The discrete assay chamber includes a first well region including at least one first well, the at least one first well being configured to receive a soluble test substance therein; a second well region including at least one second well, the at least one second well being configured to receive a sample comprising cells therein; and a channel region including at least one channel connecting the first well region and the second well region. Preferably, at least one second well is horizontally offset with respect to the first well region in a test orientation of the device.Type: GrantFiled: March 15, 2002Date of Patent: November 2, 2004Assignee: Surface Logix Inc.Inventors: Gregory L. Kirk, Matthew Brown, Emanuele Ostuni, Enoch Kim, Bernardo D. Aumond, Olivier Schueller, Paul Sweetnam, Brian Benoit

Patent number: 6661004Abstract: An apparatus and method are provided for processing the images obtained from an atomic force microscopy when profiling high aspect ratio features. A deconvolution technique for deconvolving the sample image includes the use of multiple images but does not require exact calibration of the scanning probe. In one embodiment, erosion and dilation techniques are used to obtain an undistorted image of the sample being measured. In another embodiment, Legendre transforms are used to obtain an undistorted image of the sample being measured. Also described is a technique for measuring the tip radius of the scanning probe.Type: GrantFiled: February 21, 2001Date of Patent: December 9, 2003Assignee: Massachusetts Institute of TechnologyInventors: Bernardo D.

Patent number: 6489611Abstract: Apparatus and methods are provided for using atomic force microscopy for profiling high aspect ratio features. Probe landing techniques include scanning prior to bringing the probe into contact with the feature. In one embodiment, the probe assembly cantilever is brought into contact with the feature and subsequent scanning is used to locate the feature with the probe. In another embodiment, the probe is moved in a scanning pattern in progressively lower horizontal planes until the probe contacts the sample feature. Also described is a deconvolution technique for deconvolving the sample image and a technique for measuring the tip radius of the feature.Type: GrantFiled: September 30, 1999Date of Patent: December 3, 2002Assignee: Massachusetts Institute of TechnologyInventors: Bernardo D.
