abstract

Particle navigation is performed for a variety of reasons including but not limited to drug delivery, cell isolation, sorting and filtering, and cell counting. Current methods accomplish these tasks by ‘tagging’ which has many benefits but also limitations in some cases. This paper proposes a novel device for nonmagnetic non-contact in-vitro particle navigation. The device is based on an idea that utilizes ferrofluids in connection with magnetic fields while effectively removing carriers as required by tagging methods and thus eliminating challenges associated with them. Analytic solution approaches and preliminary results show that this technology has promising potential to profoundly impact the field.
