Abstract:

This progress report has two parts. The first part reports progress to date on the development of a common-path, optical heterodyne fiber sensor for remote monitoring of the electrically induced birefringence of cells and tissue. The second part is a report from Professor John P. Wikswo of Vanderbilt University, who is a sub-contractor on the University of Maryland contract. He is working on the development of a very small SQUID NanoSQUID , which will allow monitoring of the magnetic fields from cells and tissues within about 2mm of tissue at physiological temperature. The SQUID is at - 4K. RA 3 Stimuli Birefringence Microwave monitoring Cell magnetic fields Cell electric fields Squid.
