Figure 2.
Frequency sweep profile of (A) HG1, HG2 and HG3 at room temperature (25.0 ± 0.5 °C); (B) HG1, HG2 and HG3 at skin temperature (32.0 ± 0.5 °C); (C) HG1-MB12.5 and HG1-MB75 at room temperature (25.0 ± 0.5 °C) and (D) HG1-MB12.5 and HG1-MB75 at skin temperature (32.0 ± 0.5 °C). Notes: The storage modulus G’ are the filled symbols and the loss modulus G” are the empty symbols.The SDs have been omitted for clarity; however, in all cases, the coefficients of variation of the triplicate analyses were less than 10%.
