  • Nonspherical microparticles and method therefor
    Patent number: 4743507
    Abstract: A method for producing nonspherical particles including those of prolate spheroidal, oblate spheroidal, and ellipsoidal shape is described. A microparticulate latex can be produced wherein the microparticles in the latex are substantially identical in all dimensions. The overall shape, volume, and aspect ratio or aspect ratios of the particles can be systematically controlled. Non-spherical particles ranging in sizes from about 0.01 microns to about 100 microns can be produced from a variety of polymeric materials. Such particles can be used as model particles for a variety of scientific studies, calibration standards for electron microscopes, and in a variety of optical, thermal, electrical, and biomedical applications.
