Fiber optic sensor measures tiny magnetic fields

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an alternative to the magnetic ...

Novel sensors could enable smarter textiles

A team of engineers at the University of Delaware is developing next-generation smart textiles by creating flexible carbon nanotube composite coatings on a wide range of fibers, including cotton, nylon and wool. Their discovery ...

Taking a closer look at unevenly charged biomolecules

In clinical diagnostics, it is critical to monitor biomolecules in a simple, rapid and sensitive way. Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face ...
