Abstract : A method for measuring the magnetic susceptibility of single cell particles in the 5 to 50 micron range was developed. The method has been used to explore the magnetic properties of several biological cellular systems. The most successful results have been obtained with red blood cells. The blood cells within a given sample appear to have a slight spread of magnetic susceptibility about an average value which corresponds well with a macroscopic measurement on many cells. Normal and spherated blood cells have been studied at different oxygen saturation conditions by both single particle and macroscopic techniques. New experimental techniques for measuring magnetic properties of particles smaller that 5 microns have been explored. (Author)
