| 20120040383 | Methods and Kits Relating To Metabolite Biomarkers For Colorectal Cancer - Embodiments of the present invention provide methods of assessing metabolite biomarkers to diagnose, monitor, prognose and treat colorectal cancer, as well as kits and systems in use thereof. In some embodiments, the metabolite biomarker profile of an subject suspected of having colorectal cancer may be compared to the metabolite biomarker profile of a healthy subject to determine if there are differences between the profiles indicative of colorectal cancer. In some embodiments, the stage of a subject's colorectal cancer may be determined. In certain embodiments, the metabolite biomarker profile of an subject may be useful in determining method of treatment for colorectal cancer. In other embodiments, the metabolite biomarker profiles of an subject having colorectal cancer may be compared prior to and after treatment to determine if there are differences between the profiles indicative of decreased colorectal cancer morbidity. | 02-16-2012 |

This composition can be provided in the form of a liquid or in a number of dry formats including a wafer, impregnated material, coated well or a tablet. The assay can be performed in described apparatus comprising a well which can be provided with a removable air-tight seal. In one optional form, the well may have a swaged rim for retaining a disc or ring inside the well and hinged plugs. This assay is useful for detecting | 10-17-2013 |
| 20140030747 | NANOCHANNEL-BASED SENSOR SYSTEM FOR USE IN DETECTING CHEMICAL OR BIOLOGICAL SPECIES - A sensor system for detecting a chemical or biological species includes a sensing element and a bias and measurement circuit. The sensing element includes nanochannels having an outer surface functionalized for interaction with the species to create a surface potential, and each having a sufficiently small cross section to exhibit a shift of differential conductance into a negative bias operating region by a shift amount dependent on the surface potential. The bias and measurement circuit applies a bias voltage across two ends of the nanochannels sufficiently negative to achieve a desired dependence of the differential conductance on the surface potential. The dependence has a steeply sloped region of high amplification substantially greater than a reference amplification at a zero-bias condition, thus achieving relatively high signal-to-noise ratio. The bias and measurement circuit converts the measured differential conductance into a signal indicative of presence or activity of the species. | 01-30-2014 |
