Low Frequency Electrorotation of Fixed Red Blood Cells
Electrorotation of fixed red blood cells has been investigated in the frequency range between 16 Hz and 30 MHz. The rotation was studied as a function of electrolyte conductivity and surface charge density. Between 16 Hz and 1 kHz, fixed red blood cells undergo cofield rotation. The maximum of cofie...

| description | Electrorotation of fixed red blood cells has been investigated in the frequency range between 16
Hz and 30
MHz. The rotation was studied as a function of electrolyte conductivity and surface charge density. Between 16
Hz and 1
kHz, fixed red blood cells undergo cofield rotation. The maximum of cofield rotation occurs between 30 and 70
Hz. The position of the maximum depends weakly on the bulk electrolyte conductivity and surface charge density. Below 3.5
mS/m, the cofield rotation peak is broadened and shifted to higher frequencies accompanied by a decrease of the rotation speed. Surface charge reduction leads to a decrease of the rotation speed in the low frequency range. These observations are consistent with the recently developed electroosmotic theory of low frequency electrorotation. |
