Concentration dependent change in the rotational correlation time (τc) of spin label in HT-29 colon cancer cells at 298 and 310 K: a) from computer simulation, b) calculated from direct evaluation of spectra. The degree of significance was denoted as follows: *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001 with respect to control sample
