    Abstract: A cellular diagnostic array has been developed that provides accurate and reproducible measurements of the physical parameters of individual cells en masse, including cell membrane surface area, cell volume, and excess membrane. Three differing patterns are employed. In the first design, a gradient array having rectangular shaped channels is used to capture cells and readily show the ratio of volume to surface area for the captured cell. The second silicone rubber array provided by the present invention employs an array of wedge shaped pipettes, each of which captures an individual cell. The position of the cell within a wedge is enough to rapidly determine the cell's actual surface area and volume. A third type of cellular diagnostic array according to the present invention employs an array of channels designed to deform a cell to study how well the cell responds to repeated deformations.

    Abstract: A system is disclosed that enables the automated measurement of cellular mechanical parameters at high throughputs. The microfluidic device uses intersecting flows to create an extensional flow region where the cells undergo controlled stretching. Cells are focused into streamlines prior to entering the extensional flow region. In the extensional region, each cell's deformation is measured with an imaging device. Automated image analysis extracts a range of independent biomechanical parameters from the images. These may include cell size, deformability, and circularity. The single cell data that is obtained may then be used to in a variety of ways. Scatter density plots of deformability and circularity may be developed and displayed for the user. Mechanical parameters such as deformability and circularity may be gated or thresholded to identify certain cells of interest or sub-populations of interest. Similarly, the mechanical data obtained using the device may be used as cell signatures.

    Abstract: This invention provides new methods and apparatus for rapidly analyzing single bioparticles to assess their material condition and health status. The methods are enabled by a resonant cavity to measure optical properties related to the bioparticle size and refractive index. Refractive index measurements are useful for determining material properties and biomolecular composition of the bioparticle. These properties and composition are dependent on the health state of the bioparticle. Thus, measured optical properties can be used to differentiate normal (healthy) and abnormal (diseased) states of bioparticles derived from cells or tissues. The methods are illustrated with data obtained from a resonator with a gain medium. The invention also provides new methods for multiple measurements in a single device, analyzing and manipulating bioparticles that are much smaller than the wavelength of light, and provides a microfluidic transport chip to enable rapid single bioparticle analysis of large populations of bioparticles.
