Nanodiamonds Shine New Light on Bio Applications
Defect complexes in nanodiamond particles, which consist of vacancies trapped by nitrogen atoms, form different color centers depending on the nitrogen state present in the diamond. New research into these color centers indicates that nanodiamond particles are ideal for molecular-imaging and cell-labeling bioprobe applications.

Tested in mice, the probe detected the activity leading to cartilage loss in joints. As the osteoarthritis progressed, the probes’ brightness levels increased. This was the first study to demonstrate that NIR fluorescence can be used to detect osteoarthritis changes, according to a research team led by Tufts University School of Medicine.

Modified Genes Triggered by Blue Light
Crossing a bacterium’s viral defense system with a flower’s response to the sun yields a light-based trigger for genes. This type of control could enable deeper study of specific genes’ functions, create complex systems for growing tissue and perhaps healing technologies, according to researchers at Duke University.

Biophotonic Imaging for Medicine: A Digital Conference
Thu, Jun 11, 2015 1:00 PM - 5:00 PM EDT
FREE WEBINAR
|
Researchers from around the world will present their latest work at “Biophotonic Imaging for Medicine: A Digital Conference.” The online event will feature a series of 15- and 30-minute talks, each followed by a brief question-and-answer period.
Presentations will focus on a range of light-based imaging and microscopy techniques for diagnosing and assessing illness, and for studying other attributes and functions of biological tissue in a medical context. Topics include photoacoustics, adaptive optics, light-sheet microscopy, optical coherence tomography, spectroscopy for biomedical research and image-guided procedures.
