This study aims to prepare, optimize, and characterize magnetic-field-sensitive sugar-templated polydimethylsiloxane (PDMS) sponges for localized delivery of an anticancer drug, 5-fluorouracil (FLU). For this purpose, different concentrations of carbonyl iron (CI) and magnetite Fe₃O₄ nanopowders were embedded as magnetosensitive materials in PDMS resins for the fabrication of macroporous sponges via a sugar-template process. The process is environmentally friendly and simple. The fabricated interconnected macroporous magnetic particles loaded PDMS sponges possess flexible skeletons and good recyclability because of their recoverability after compression (deformation) without any breakdown. The prepared magnetic PDMS sponges were evaluated for their morphology (SEM and EDS), porosity (absorbency), elastic modulus, deformation under a magnetic field, thermostability, and in vitro cell studies …
