ABSTRACT
Magnetic materials are readily manipulated through “action from a distance” by using magnetic fields, enabling on-demand control over their assemblies. Our first approach magnetizes materials by amalgamating nonmagnetic and magnetic nanoparticles. These hybrid materials are further functionalized with physical or biological materials and formulated into magnetic inks. The second approach suspends nonmagnetic particles directly within a fluid containing a dissolved paramagnetic salt. We will discuss several applications, including rapidly printed biosensors that detect biomarkers and pathogens, printed electrochemical energy storage devices, microwave wave absorbing paints, and rapid biological cell assemblies such as cancer tumour surrogates for drug discovery
