Physical Characterization of Magnetic Bacteria and Their Electromagnetic Properties in the Frequency Range 1-400 GHz
Abstract
Samples have been prepared for electromagnetic measurements. Magnetic bacterial cells were freeze-dried following gluteraldehyde fixation. About 1 gram of freeze-dried following gluteraldehyde fixation. About 1 gram of freeze- dried cells was thoroughly dispersed in a special mixture consisting of lanolin, vaseline, and paraffin, 1:1:1 by weight. This mixture forms a low melting point (50C), low EM absorbing fluid. Sample holders were made by machining 3-inch diameter dishes out of polyethylene, another low absorption material. In initial experiments, an empty dish, a dish filled with the suspension fluid, and a dish filled with the cells in the suspension fluid will be measured in order to determine the absorption characteristics of the cells themselves. Additional measurements will be tried with freeze-dried cells suspended in liquid hexane. Ultimately, it is hoped that suspensions with aligned cells can be prepared by allowing the suspension mixture to solidify in external magnetic fields.
