Abstract: The present invention (also identified as “Capacitance cytometry”) relates to microfluidic and nanofluidic devices for detecting or measuring an electrical property of a fluid (liquid or aerosol), a single molecule, particle, or cell in fluid. In a particular embodiment, the devices detect or measure changes in capacitance of a fluid, molecule, particle or cell as it passes through the device. The invention relates to detection and measurement of single molecules, particularly biological molecules, and to methods of sequencing polynucleotide molecules (RNA or DNA) by detecting differentially labeled single nucleotides. Single molecule detection applications include DNA or RNA sequencing, detection of SNPs, protoemics, and particle sizing. The device can be used to determine cell DNA content, to analyze cell-cycle kinetics of cell populations, and to assay for abnormal changes in cell DNA content.

Abstract: Assays for determining the downstream effects of drugs that modulate the function of transcription regulatory proteins are disclosed. The assays comprise the steps of (a) providing cells that contain the transcription factor; (b) maintaining a control population and a test population of the cells under conditions that allow gene expression to occur in the cells, wherein the test population is exposed to the agent that modulates the activity of the transcription factor; (c) generating a gene expression profile for each of the control population and the test population of cells; and (d) comparing the gene expression profile from the control population of cells with the gene expression profile from the test population of cells; those differences being attributable to the effect of the agent that modulates the activity of the transcription factor.
