  • Can magnetic polyacrylamide hydrogel promote multicellular spheroids?
  • Gu et al. reported a magnetic polyacrylamide hydrogel with cell adhesion microarray interface, [ 25] which can effectively promote the formation of multicellular spheroids. It is considered as a prevailing tool to study the microenvironmental regulation of therapeutic problems and tumor cell physiology.
  • Can magnetic apatite nanoparticles enhance hydrogels?
  • It has been demonstrated that magnetic apatite nanoparticles introduced into poly (vinyl alcohol) (PVA)/sodium alginate hydrogel could generate magnetic response and enhance hydrogels. [ 46] When pH = 4.5, the maximum adsorption capacity of nano-beads for bovine serum albumin was the highest, reaching 127.3 mg·g −1.
  • Can magnetite and hydrogel matrix adsorb heavy metal ions and dyes?
  • As shown in Table 1, the combination of magnetic additives (such as magnetite) and hydrogel matrix can simultaneously adsorb contaminants such as heavy metal ions and dyes. Some MHs have a removal rate of more than 99.5%. Moreover, the optimized MHs has high-sensitivity, high-selectivity, fast-adsorption and reusability. TABLE 1.
  • What is a soluble magnetic alginate particle (Mam)?
  • The scaffold was constructed by adding soluble magnetic alginate particles (MAM) containing nano-iron oxide to the hydrogel precursor solution. The diameter of MAM is 100 nm∼20 µm, and a concentration of 5 mg mL -1 of MAM is the upper-limit allowing for optimal chain length on the millimeter scale.
