Investigation of swelling mechanisms in self-adherent microneedles

Swellable microneedles (MNs) expand to mechanically interlock with wet biological tissue, offering improved adhesion and enhanced drug delivery over non-swellable counterparts. This study numerically evaluates how the material and geometric parameters of swellable MN arrays influence shape change. U...
