Magnetically Responsive

Magnetically responsive describes materials, cells, or engineered biological systems that change position, orientation, shape, or activity when exposed to a magnetic field, enabling noncontact control. The response arises when magnetic moments or embedded magnetic particles interact with an external field, producing attraction, repulsion, torque, or field-guided movement; its strength depends on field conditions and material properties. In developmental biology, magnetically responsive tools can help position cells, organize multicellular structures, and apply controlled mechanical cues, supporting studies of morphogenesis, tissue assembly, and how physical forces influence developmental patterning.

Source: Kuhn, Y. et al. Intracortical Inhibition Within the Primary Motor Cortex Can Be Modulated by Changing the Focus of Attention. J. Vis. Exp. (2017)This video demonstrates the use of transcranial magnetic stimulation (TMS) to modulate motor neuron activity and measure muscle responses via electromyography (EMG). It outlines the steps for locating the motor hotspot, determining stimulation thresholds, and assessing the effects of subthreshold TMS (subTMS) on cortical inhibition.

We present a facile method to fabricate a biodegradable gelatin-based drug release platform that is magneto-thermally responsive. This was achieved by incorporating superparamagnetic iron oxide nanoparticles and poly(N-isopropylacrylamide-co-acrylamide) within a spherical gelatin micro-network crosslinked by genipin, in conjunction with an alternating magnetic field application system.

Cell surface adhesions are central in mechanotransduction, as they transmit mechanical tension and initiate the signaling pathways involved in tissue homeostasis and development. Here, we present a protocol for dissecting the biochemical pathways that are activated in response to tension, using ligand-coated magnetic microbeads and force application to adhesion receptors.

Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN Magnetic fields can be generated by moving charges, such as an electrical current. The magnetic field generated by a current can be calculated from the Maxwell equation. In addition, magnetic objects such as bar magnets can also generate magnetic fields due to microscopic dynamics of charges inside the material. Magnetic fields will exert magnetic force on other moving...
