Abstract
In article 2000118, Sukho Park and co-workers propose a bilayer hydrogel sheet-type intraocular microrobot consisting of a therapeutic layer and an magnetic nanoparticles (MNPs) layer. The bilayer hydrogel microrobot capable of locomotion using a magnetic field can accurately move to a target lesion, dissolve the therapeutic layer by alternatingmagnetic field (AMF), deliver encapsulated drugs to the target lesion, and retrieve the remaining MNPs layer.
