Light-based sensor can detect low concentrations of cancer biomarkers in the blood

by

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to spot early signs of cancer and other conditions using a simple blood test. Biomarkers such as proteins, DNA or other molecules can be used to … Read more

Flowing quantum dots produce one million pulses in a second

by

Laser technology is going to play an important role in advancing quantum devices, healthcare tools, and optical computing applications. However, a key problem with most modern lasers is that they emit light at fixed wavelengths. This limitation can be overcome using quantum dots, nanoscale semiconductors that can emit light of different colors depending on their … Read more
