Figure 3.
Thermosensitive and magnetic responsiveness of hydrogels. (A) Photographs of the (a and b) CS/GP hydrogel at 25°C and 37°C, and (c and d) CS/GP/Fe3O4/DXM hydrogel at 25°C and 37°C; (B) Variations in the storage and loss moduli (G' and G", respectively) with angular frequency at 37°C; (C) Photographs of the (a) CS/GP/Fe3O4/DXM hydrogel sunk to the bottom of beaker with saline and (b) CS/GP/Fe3O4/DXM hydrogel attracted to the left of beaker having a 0.4-T magnetic field. The arrows indicate the direction of motion of CS/GP/Fe3O4/DXM hydrogel.
