Polarization-Sensitive OCT Monitors Tooth Decay
Nondestructive polarization-sensitive OCT is likely to become a useful addition to the dentist’s armamentarium for assessing the depth and internal structure of lesions related to tooth decay. It also may be extremely valuable to dental researchers for assessing new anticaries agents. Currently in the US, dental decay is often detected using visual/tactile methods coupled with radiography....

Editorial
Biophotonics Rising
When BioPhotonics International magazine launched in 1994, then-publisher Wendy A. Laurin wrote, “As you look through this first issue, we hope you will share our sense of awe at the increasing number of ways that photonic technology is becoming an integral part of the medical and biophotonic scene.” And that was before the first now-ubiquitous smartphones rolled off the assembly...
BioScan
Creating order from disorder
Light scattering makes clear imaging through an opaque material seem insurmountable, but researchers have discovered that the resulting speckle pattern actually contains the key to restoring the shape of the original object. The findings could have important applications in bioimaging. The speckle pattern “is not completely random but contains some subtle correlations. We realized that the...
DNA origami nanolenses visualize single modules
Self-assembling nanolenses that use DNA as a construction material represent a better way of visualizing single molecules and could help unlock biological processes such as DNA transcription or...
