Day 1 continued: Learning to See Through Walls

Is it possible to look inside an object using only light reflected off the front?  Can you transmit more light through an attenuating medium by making it even thicker?  Could a bank verify your identity using the pattern of light scattered off your teeth?

How to fit a laser-scanning microscope into a 2mm diameter tube

Optical microscopy can provide high-resolution images of cellular morphology and matrix organization, which can be utilized to diagnose disease or trauma. However, achieving an adequate signal-to-noise ratio at imaging depths exceeding 1mm is very challenging.  As a result, the initial clinical applications for optical microscopy techniques have largely focused on skin pathology. ...

It takes blood, sweat, and SERS to image single cells

Throw out those old dusty fluorescent molecules and welcome in the next generation of optical contrast agents. SERS (Surface Enhanced Raman Scattering/Spectroscopy) nanoparticles are sophisticated new contrast agents that offer some distinct advantages over conventional fluorescent molecules for investigating molecular biology.

Where would biomedicine be without optics?

Much of the emphasis in biomedical optics research has been placed on the clinical translation of our technologies -- and rightfully so!  As my fellow blogger Dr. Ken Tichauer indicates, the potential impact in the clinic is great and the future remains bright.  But as we gear up for OSA BIOMED 2014 in Miami, I will be excited to learn about some of the latest applications in basic...
