Bio-optics and bio-optical materials

Prof. Alison Sweeney and her colleagues believe that the reflective structures in giant clams help them grow algae. The clams use sub-wavelength structures formed from a protein called reflectin to optimize the photosynthesis of the algae living in the clam tissues.

SDSS Galaxy Survey

The UPenn Fit Catalog provides 2-d galaxy profile fits in several visible bands using SDSS data.  Additional data collected from other sources is provided to facilitate analysis. The catalog is constructed and maintained by Professor Mariangela Bernardi and her group.

 

Large Synoptic Survey Telescope Site

Self-assembling Building Blocks

Self-assembling building blocks occur in a diverse set of supramolecular, macromolecular, and other complex systems that impact numerous fields such as industrial dyes and pigments, xerographic receptors, organic semiconductors, transistors, light-emitting diodes and solar cells.  Prof. Paul Heiney collaborates with chemists and material scientists on the study of such molecular systems.

 

DNA through a Solid State Nanopore

Dr. Meni Wanunu, Dr. Marija Drndic and others at the University of Pennsylvania have threaded DNA through solid state nanopores in order to gain information about chemically modified DNA. The image depicts chemically modified DNA translocating through a nanoscale pore in silicon nitride.
