Handheld Scanner Diagnoses Diseases

Medical science has progressed to such extent that a handheld nuclear magnetic resonance (NMR) scanner has been developed, capable of diagnosing diseases and identifying pathogens on-the-go. This scanner is highly portable, being numerous times smaller compared to standard NMR spectroscopy machines. This is made possible by lining up nuclei in a sample using a powerful magnetic field and then zapping them with radio waves that cause them to wobble, or precess. The prototype is sensitive enough to detect a mere 10 bacteria in samples, and can also double up as a gizmo to test for water purity as well as gaseous samples. The design patent has already been filed, and the final product will be marketed in the near future.
