A web cast on December 9, will feature Dr. Tanya Dahms, professor in the Department of Chemistry and Biochemistry, and Dr. Heiko Haschke, JPK Instruments, Germany., part of the Nature Publishing Group, provides over 6 million visitors a month with access to publications; including Nature, the world’s most highly cited interdisciplinary science journal, and online databases and services.
“This webcast is a tremendous opportunity to introduce my lab and research to a worldwide audience,” says Dahms. “Being invited to present our work, highlights that we are on the cutting edge of research in this area.”

Dr. Haschke will first provide an overview of the latest in atomic force microscopy (AFM) based technology and how it is now possible to study dynamic processes allowing users to obtain high-resolution images of soft samples and map nano-mechanical information. He will also demonstrate the simultaneous imaging of living fibroblasts (the most common cells of connective tissues in animals) using AFM and stimulated depletion emission microscopy.

Dr. Dahms will then discuss her work systematically characterizing the sublethal effects of xenobiotics (foreign chemical substances found within an organism), including the 2,4-D herbicide, on microbial physiology using AFM, confocal microscopy, metabolomics and traditional biochemical assays. 

She will also describe how combining AFM with laser scanning confocal microscopy can be used to develop high-content assays that offer a more complete picture of biological systems by providing simultaneous information on cell physiology, surface structure and properties with high sensitivity and resolution.  

“The research focus of my lab at the U of R is primarily on the impact of external stimuli on target and non-target organisms probed using a variety of microscopy techniques,” says Dahms. “The integration of surface scanning and optical microscopes represents a new era in microscopy, allowing researchers to simultaneously explore a sample’s interior and exterior with broad application to many systems.”
