Electrorheologically-Controlled Drug Release

Electrorheologically-Controlled Drug Release Electrorheological effects refer to a possibility of controlling viscosity of a colloid system by applying an external electric field that can lead both to increased and decreased viscosity.

Typically, as much as several orders of magnitudes in the viscosity changes can be reached and this effect could be practically utilized for a controlled drug delivery. With a proper design of the nanoparticulate drug carriers, the motion behavior of drug particles or the viscosity of carrying medium can be exquisitely manipulated by applying relatively low external electric field generated by a small battery. This technology opens many prospects of the active control of the drug delivery profile with increased efficiency and specificity compared to many traditional formulation approaches.
