Disclosed is a method and device for detection ofin breath emissions utilizing an unlabelled urea, in which a patient ingests a safe quantity of unlabelled urea. After ingestion, expired breath of the patient is analyzed for ammonia, with a detection based on levels of ammonia lower than 50 parts per billion to 500 ppm to detect

Detection of H. pylori utilizing unlabeled urea

The present invention relates to gas sensors using doped ferroelectric materials. The sensors can be fabricated as an array where different portions of the array can operate at different independently controlled temperatures to detect different gas phase components of a gas sample. Preferred embodiments can be used for the diagnosis of conditions, such as, diabetes.

Selective chemosensors based on the ferroelectric materials, mixed oxides, or temperature modulation of oxide polymorph stability

Reliable, fast and inexpensive breath gas detector systems for medical diagnostics, including personal, handheld monitoring devices for a variety of diseases and conditions, including, for example, asthma, diabetes, blood cholesterol, and lung cancer. A sensor device () for detecting gases includes a sensing element () having an electrical resistance that changes in the presence of a target gas; a readout circuit, electrically coupled to the sensing element due to the presence of the target gas and converts the measurement to a digital signal; and a feedback loop () from a digital unit () to the readout circuit to compensate for variations in a baseline resistance of the sensing element.

Gas sensor with compensations for baseline variations

An apparatus is for detecting the presence of selected gaseous compounds indicative of a medical condition includes a probe having one or more sensor elements having a conductivity which is responsive to the presence of selected gaseous compounds, at least one sensor element containing a transition metal oxide selected from the group consisting of WO, beta-MoOand UO; and means for measuring the conductivity of each said sensor element.

Selective nanoprobe for olfactory medicine

Single crystal MOnanowires were produced using an electrospinning technique. High resolution transmission electron microscopy (HRTEM) revealed that the 1-D nanostructures are from 10-20 nm in diameter, on the order of 1-2 &#x3bc;m in length, and have the orthorhombic MOstructure. The structure, crystallinity, and sensoric character of these electrostatically processed nanowires are discussed. It has been demonstrated that the non-woven-network of MOnanowires exhibits higher sensitivity and an n-type response to NHas compared to the response of a sol-gel based sensor.
