What if a person with diabetes could measure blood sugar without a pinprick? What if a quick scan of a person’s breath could reveal how their kidneys are doing or whether they have asthma?
Researchers have demonstrated a method for identifying nitric oxide gas using lasers and sensors that are inexpensive, compact and highly sensitive, a portable device that could be of great value to atmospheric science, pollution control, biology and medicine.
Princeton researchers traveled to China to study changes in Beijing’s air quality during the Olympics, when the Chinese government dramatically cut vehicle and factory emissions.
A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring and medical diagnostics.
A little clay and sawdust went a long way at Princeton this month when a group of Trenton-area high school students used the simple materials to create effective, low-cost water filters.
The National Science Foundation has funded a multimillion-dollar Engineering Research Center based at Princeton University that is expected to revolutionize sensor technology, yielding devices that have a unique ability to detect minute amounts of chemicals found in the atmosphere, emitted from factories or exhaled in human breath.
