Anisotropic Contraction in a Magnetically Hard but Mechanically Ultra‐Soft Foam for Precise Drug Delivery (Adv. Mater. Technol. 4/2023)

Abstract

Precise Drug Delivery In article number 2201255, Zhigang Wu and co‐workers present an ultra‐soft hard magnetic foam, which undergoes an anisotropic contraction under an applied magnetic field and has the ability of flexible locomotion. Such a new foam is utilized for precision drug delivery since it allows adjustable drug release rate and no leakage, and no residues during delivery.
