The capabilities of the Advanced Photon Source, one of the world's premier facilities for x-ray science, are being used for the study of biological systems at length scales from molecules to organisms.Recent advances have greatly expanded the potential of these techniques. Phase-contrast, x-ray fluorescence microscopy, coherent diffraction imaging and x-ray solution scattering each have distinct capabilities for addressing specific biological questions.

In this talk, I will provide specific examples of the application of each of these techniques and I will discuss future directions in the use of x-rays for the study of biological systems.

NONLINEAR RAMAN MICROSPECTROSCOPY:
APPLICATIONS TO BIOMEDICAL IMAGING AND SENSING

Progress in the Life Sciences has always depended on the development of new tools and instruments. Our ability to understand the functions of living systems on a cellular and molecular level is greatly enhanced by imaging techniques capable of providing structural and chemical information in vi vivo. The simplicity, availability, and non-invasiveness of optical methods are attractive features for fundamental physiological studies in small animals, disease diagnosis, image-guided surgery and posttreatment recovery management in patients.
At the end of my lecture I will describe a recently demonstrated intriguing possibility of combining nonlinear Raman excitation with ultrasound detection, which allows reaching a large penetration depth, while preserving chemical specificity and high spatial resolution.
