Detection of circular polarization in light scattered from photosynthetic microbes
(2009-05)
The identification of a universal biosignature that could be sensed remotely is critical to the prospects for success in the search for life elsewhere in the universe. A candidate universal biosignature is homochirality, ...
Circular polarization in scattered light as a possible biomarker
(2009)
Biological molecules exhibit homochirality and are optically active. Therefore, it is possible that the scattering of light by biological molecules might result in a macroscopic signature in the form of circular polarization. ...
