Abstract: A method of assessing gut health in a subject is provided. The method involves placing a device on or near the subject's skin and measuring a level of hydrogen gas emanating through the subject's skin. The device includes an electrochemical sensor capable of detecting hydrogen gas and a means of connecting the device to an apparatus having a central processing unit (CPU). The apparatus provides information on hydrogen gas level and the hydrogen gas level is used to assess gut health of the subject.

Abstract: A carbon nanotube-based reference electrode and an all-carbon nanotube microelectrode assembly for electrochemical sensing and specialized analytics are disclosed, along with methods of manufacture, and applications including detection of ionic species including heavy metals in municipal and environmental water, monitoring of steel corrosion in steel-reinforced concrete, and analysis of biological fluids.

Abstract: An apparatus and method of simultaneous spectroelectrochemical analysis is disclosed. A transparent surface is provided. An analyte solution on the transparent surface is contacted with a working electrode and at least one other electrode. Light from a light source is focused on either a surface of the working electrode or the analyte solution. The light reflected from either the surface of the working electrode or the analyte solution is detected. The potential of the working electrode is adjusted, and spectroscopic changes of the analyte solution that occur with changes in thermodynamic potentials are monitored.

Abstract: An apparatus 20 for the separation of a subpopulation of cells from an intact organ or other biological material is provided. The apparatus 20 includes: (1) a digestion chamber 24 that integrates the primary digestion process, (2) a measuring cylinder 26, (3) a cell collection chamber 28, (4) a heat exchanger 30 for raising and lowering temperatures in the digestion chamber 24 to activate or inactivate enzymes, (5) sensors 112, 114, 116, 118, 120, 122 to complete a closed feedback loop for allowing optimization of the digestion process, and (6) mock cells which mimic the cells to be harvested and which are used to fully optimize the process without unnecessary destruction of harvested cells. The manipulation of the digestion process may be manual or may be automated under computer control.

Abstract: The present invention provides a method of detecting targeted agents in liquid, and in particular, the detection of targeted biological agents in finished water and other liquids. The methods disclosed herein can be used for the detection of biological agents that can be used as bioterrorism agents in a bioterrorism attack.

Abstract: An infant incubator in which the controls and displays are provided in a module which is in proximity to but spaced from and above the hood of the incubator at generally the eye-level of a standing adult.
