Laboratory: NASA Ames Research Center Technology: Low-power compact nanosensor array chip Opportunity: Available for licensing Details: NASA has developed an innovative approach to improve the quality and convenience of medical diagnosis, and data transmission for immediate therapy. The new technology uses a network of nanochemical sensors on a silicon chip combined with a monitoring system composed of humidity, temperature, and pressure/flow sensors for real-time chemical and physical properties measurement of human breath for noninvasive and low-cost medical diagnosis. No such technology exists in the market today. Although many research activities are ongoing, NASA's technology is readily available for this application. The nanosensor array chip provides a highly sensitive, low-power, and compact tool for in-situ and real time analysis. It changes the way and time decisions are made to help both the patient and the medical care provider minimize their cost, optimize resources, reduce risk, and cut the amount of time needed for conducting a response. Many diseases are accompanied by characteristic odors. Recognizing those odorscan provide diagnostic clues, guide the laboratory evaluation, and affect the choice of immediate therapy. A number of volatile compounds, called biomarkers, are found in breath samples—for example, the presence of acetone with other biomarkers can indicate Type I diabetes. NASA's invention utilizes an array of chemical sensors combined with humidity, temperature, and pressure for real-time breath measurement to correlate the chemical information in the breath with the state and functioning of different human organs. This tool provides a noninvasive method for fast and accurate diagnosis at the medical point of care or at home. The sensor chip includes multisensors for a comprehensive measurement of chemical composition, temperature, humidity, and pressure/flow rate. The sensor data collected from this chip can be wired or wirelessly transmitted to a computer terminal at the doctor's desk or hospital monitoring center. The sensor chip can be connected directly or via universal serial bus (USB) to a cell phone for data transmission over a long distance and can receive instructions from a doctor's office for an immediate therapy.
