Stanford University develops a handheld portable ammonia detector

The H-H of Stanford University Medical College, one of Stanford University Interdiscies, is sitting next to the table and puts forward a one-on-one idea of ​​cooperative research. Inspired by the nearest medical puzzle, Stanford University Medical (Oncology) and Biochemistry Professor Gilbert Chu (Gilbert Chu) issued a call, requiring chemists to help him create a quick, easy and accurate measurement of ammonia The content of the sensor. Just below the table, Matthew Kanan, Matthew Kana, recorded a surprising congenital: Thomas Veltman, is studying an ammonia used to measure any liquid. sensor. In ACS Sensors, Chu, Kanan, Veltman and colleagues published their partnership products: a hand-held portable ammonia detector, like a blood glucose meter for measuring blood sugar, From your finger or ear puncture. Ammonia is digestive natural product, usually processed into urea by the liver, and then excreted by urine. Ammonia in the blood will lead to mental and physical obstacles, which is concerned about people with liver disease or genetic situations that hinder ammonia metabolism. New equipment may be particularly beneficial to newborns with these metabolic diseases. In this population, brain damage may occur within a few hours of raising ammonia levels, and for treatment, some families must travel long distances to get enough tests. Natalia Gomez-Ospina said: "I have discussed this kind of equipment with a child with this situation, which will make them emotions, because They are not properly and quickly examining the consequences of ammonia. Professor of pediatric science assistants, the same person in the papers. This may change life for these families. The sensor has been tested for blood samples of patients with increased ammonia levels, and the portable version of the device has been tested for ammonia water samples. The result is accurate in both cases. Now, researchers are adjusting to the design and manufacturing of the equipment, in order to prepare a study for the assessment of the US Food and Drug Administration (FDA). Read more
