Abstract
A method for magnetic cellular manipulation may include contacting a composition with a biological sample to form a mixture. The composition may include a plurality of particles. Each particle in the plurality of particles may include a magnetic substrate. The magnetic substrate may be characterized by a magnetic susceptibility greater than zero. The composition may also include a chargeable silicon-containing compound. The chargeable silicon-containing compound may coat at least a portion of the magnetic substrate. The biological sample may include cells and/or cellular structures. The method may also include applying a magnetic field to the mixture to manipulate the composition.
