How Moist Heat Kills Spores of Bacillus subtilis
(East Carolina University, 2007-12)
Populations of Bacillus subtilis spores in which 90 to 99.9% of the spores had been killed by moist heat gave only two fractions on equilibrium density gradient centrifugation: a fraction comprised of less dense spores ...
Laser tweezers and Raman spectroscopy systems and methods for the study of microscopic particles
(2005-05-24)
Methods and systems for studying microscopic particles are provided. An optical trap for a selected microscopic particle can be formed with a laser beam at a first power level. The laser beam can have a variable power level ...
