First microlasers capable of detecting individual molecules and ions could one day aid diagnosis

Scientists have created the first microlasers capable of detecting individual molecules and even single atomic ions, a breakthrough that could significantly advance early disease diagnosis and molecular-scale medical testing. Researchers at the University of Exeter's Living Systems Institute have published their work in Nature Photonics. The paper opens up new possibilities for microlaser biosensing technology, including "lab-on-a-chip" technology capable of instant medical testing and diagnosis.
