Bright Ideas — New Photonic Chip Yields Higher-Contrast Microscopy, OCT Imaging Goes Deeper Into Skin
12/8/2021
Bright Ideas presents the most captivating news and innovations in photonics. This week, Chinese researchers presented a new planar photonic chip that doesn’t require a "bulky" condenser or special objective to conduct darkfield or total image reflection (TIR) microscopy. A new DARPA Young Faculty Award recipient is exploring a ne way to control the propagation of light that would enhance power efficiency and thereby improve communications technologies. And, biomedical engineers have found a way to increase optical coherence tomography (OCT) depth through the skin by 50 percent.

Trapping Tiny Particles: A Versatile Tool For Nanomanipulation
7/27/2020
Nanoparticles are tiny. At just 1/1000th of a millimeter, they’re impossible to see with the naked eye. But, despite being small, they’re extremely important in many ways. If scientists want to take a close look at DNA, proteins, or viruses, then being able to isolate and monitor nanoparticles is essential.
