Abstract
In this report, a method to measure cytoplasmic viscosity using a nano machine was proposed. We fabricated magnetically driven nano machine by spattering nickel on the suface of carbon nano coil. The nano machine was introduced into the epidermal cell of commelina communis using microinjection. We calculated cytoplasmic viscosity by measuring the magnetic flux density of the nano machine when losing steps. As the magnetic field gets weaker, the nano machine eventually loses its steps. The relationship between the viscosity and the magnetic flux density applied to the nano machine when losing steps is given by η=kB^2, where k is the coefficient for each nano machine. Based on this theory we measured the cytoplasmic viscosity of commelina communis and obtained the viscosity of 1.1±0.2 mPa・s.
