UNLABELLED The objective of this work was to examine the effects of magnet distance (and by proxy, field strength) on nanomagnetic transfection efficiency. METHODS non-viral magnetic nanoparticle-based transfection was evaluated using both static and oscillating magnet arrays. RESULTS Fluorescence intensity (firefly luciferase) of transfected H292 cells showed no increase using a 96-well Nd...

This paper reports the design, fabrication, and testing of a permanent-magnet energy harvester generator for body motion. The described generator was capable to extract up to 117μW of power from walking, employing a non-resonant rotational mechanism. The planar generator proposed is composed of a rotor having multiple NdFeB permanent magnet pole-pairs with an eccentric proof mass. The stator ha...

The conjugation of 14 nm diameter CoFe2O4 nanoparticles to the surface of biotinylated microtubules enables their manipulation with externally applied magnetic fields of small, permanent NdFeB magnets. Microtubules are selectively patterned on kinesin motor-modified glass surfaces in coparallel arrays that mimic the orientation of the magnetic field lines over millimeter distances. The magnetic...

Abstract Magnetic actuation has attracted a growing attention due to its non‐contact performance, rapid response and penetrability. The realization of magnetic requires the participation magneto‐responsive materials (MRMS), polymers (MRPs) are one most widely used MRMs. Here, we report fabrication, characterization tests neodymium‐iron‐boron‐polydimethylsiloxane (NdFeB‐PDMS) films. NdFeB‐PDMS f...
