Highly Tough, Biocompatible, and Magneto-Responsive Fe₃O₄/Laponite/PDMAAm Nanocomposite Hydrogels.

ABSTRACT: Magneto-responsive hydrogels (MRHs) have attracted considerable attention in various applications owing to their smart response to an externally applied magnetic field. However, their practical uses in biomedical fields are limited by their weak mechanical properties and possible toxicity to the human body. In this study, tough, biocompatible, and magneto-responsive nanocomposite hydrogels (MR_NCHs) were developed by the in-situ free-radical polymerization of N, N-dimethylacrylamide (DMAAm) and laponite and Fe₃O₄ nanoparticles. The effects of the concentrations of DMAAm, water, and laponite and Fe₃O₄ nanoparticles in the pre-gel solutions or mixtures on the viscoelastic and mechanical properties of the corresponding hydrogels were examined by per
