Bacteriophage Pf1 complex viscosity

Bacteriophages (phages) are viruses that attack bacteria, causing them to multiply. This requires phage orientation with respect the bacterial receptor, a necessary condition for attachment. Since phages not motile, they rely on their Brownian motion and, specifically, its rotational components reorient. We focus specifically Pf1 (the bacteriophage called pseudomonas Pf1), about which much has been written, though whose diffusivity determined from rheological measurements is known. compare general rigid bead-rod theory intramacromolecular hydrodynamic interactions our new of complex viscosity an aqueous suspension arrive at relaxation time. From this time, we get central transport property reorientation, dimensionless diffusivity, λ0Dr=2.37×10−6, differs within one order magnitude fluorescence microscopy.
