Growth of the soil bacterium Stenotrophomonas maltophilia in the presence of selenite produced a mixture of two types of cells: those that contained numerous electron-dense bodies of elemental selenium and those that did not. Light diffraction and electrical impedance measurements indicated that the

More than 15 years ago a pioneering report on the separation of cellular material using sedimentation field-flow fractionation (SdFFF) was published. Surprisingly, only a few reports on SdFFF applications to cell separations are available as yet. The major limitations which seemed to slow the develo

## TRIBUTE TO PROFESSOR J. CALVIN GIDDINGS This research article is dedicated to the memory of Professor J.C. Giddings, who invented the concept of field-flow fractionation and who first described the huge potential of these methods for biological applications. Professor Giddings's pioneering work
Most analyses of submicron particles using sedimentation field-flow Ε½ . fractionation SdFFF have been carried out in aqueous systems. However, a nonaqueous carrier solution could be suitable for SdFFF when the particle density is close to the density of water. Few papers have reported the retention
