In Optogenetics, Femtosecond Lasers Blaze New Paths
One of the most active and exciting areas in neuroscience is the use of optogenetics to unravel how neural pathways in the brain process and transmit information. Optogenetics involves the use of light-sensitive opsins — a special class of membrane-embedded proteins. Opsins are switchable channels or pumps for specific cations or anions with on or off states determined by irradiation with light of an appropriate wavelength.

Point-of-Care Photonics Deliver Vital Care in Developing Regions
Nowhere does the burden of disease weigh as heavily on people as it does in the low-resource settings of the developing world. Photonics research and innovation are making incredible strides to alter this picture through low-cost portable optical imaging devices capable of bringing improved medical diagnostics to some of the poorest regions in the world.

Retina Camera, No Dilating Required
A portable inexpensive camera that can photograph the retina could replace the need for pupil-dilating eye drops. Researchers have created a prototype camera that is small enough to carry in a pocket; it can take pictures of the back of a patient’s eye that can then be shared with other doctors or attached to a medical record.

Exposure to green LED could provide an inexpensive, non-pharmacological approach to managing chronic pain, by altering the levels of endogenous substances that potentially inhibit pain and decrease inflammation of the nervous system.

Monitoring a surgical patient’s blood with light could provide real-time status updates during life-and-death operations and could replace the need for doctors to wait while blood is drawn and tested.

BOB – Open-Design Upright Microscope
SUTTER INSTRUMENT
The BOB microscope is a compact, single assembly that mounts to the “blue rail” with one massive, stable connection. Replacing the microscope frame with an optical rail builds in the ability to adjust the overall height of the microscope.

Biophotonic Tools for Diagnosing and Treating Eye Disease
Wed, May 17, 2017 1:00 PM - 2:00 PM EDT
Retinal laser therapy has had a profound impact on the treatment of diseases such as macular degeneration and diabetic retinopathy. In this webinar, Yannis M. Paulus, M.D., will discuss novel biophotonics tools and techniques for diagnosing and treating eye diseases, including retinal laser therapies and imaging. He will present significant advances in selective, reproducible retinal laser therapy and discuss Photo-Mediated Ultrasound Therapy (PUT), a novel approach using a low intensity laser concurrently with ultrasound to selectively treat blood vessels. Dr. Paulus will also speak on new imaging modalities in ophthalmology, including optical coherence tomography, photoacoustic imaging, handheld/smartphone based imaging, and molecular imaging. Dr. Paulus is an academic vitreoretinal surgeon, an assistant professor of Ophthalmology and Visual Sciences and an assistant professor of Biomedical Engineering at the University of Michigan Kellogg Eye Center. Through his research, he seeks to help physicians diagnose diseases earlier, improve treatment monitoring, and practice precision medicine tailored to each unique patient.
