Electrorheologically-Controlled
Drug Release

The electrorheological effect refers to the possibility of controlling the viscosity of a colloid system by applying an external electrical field generated by a small battery. With proper design of nanoparticulate drug carriers, it is possible to manipulate the motion behavior of drug particles or the viscosity of the carrying medium this way.

With proper design of nanoparticulate drug carriers, the motion behavior of drug particles or the viscosity of the carrying medium can be manipulated by applying a relatively low external electrical field generated by a small battery. This technology opens up many prospects for active control of drug delivery profiles with greater efficiency and specificity than many traditional formulation approaches.
