Problems of Food Safety and Sustainability

The bacterium, E. coli O157:H7, may cause illness or death as a result of its ingestion of undercooked meat products contaminated by it.  Federal inspection agencies have mandated “zero-tolerance” for E. coli O157:H7 on beef carcasses.  Although it is possible to detect single bacteria on a carcass, this cannot be done rapidly enough to monitor a line speed of several hundred carcasses an hour. We discovered, patented, and marketed a technology based on detecting the source of the bacterium:  fecal material!

Quantum Entanglement: Exploiting the Quantum Nature of Light Permits Super-Resolution Imaging

"Schrödinger’s cat" is an example of quantum- mechanical superposition and of “quantum entanglement.”

Subdiffraction (or Super-Resolution) Imaging and Microscopy

Diffraction limits our ability to image objects.  If the object we are trying to measure is comparable in size to the wavelength of the light used for imaging, the measurement is “diffraction limited.”
