Active modulation of microdroplets using electropermanent magnets / Ali Mohamed Ali Mohamed Ibrahim ; Supervised Yasser Hussein Anis

By: Contributor(s): Material type: TextTextLanguage: English Publication details: Cairo : Ali Mohamed Ali Mohamed Ibrahim , 2017Description: 81 P. : facsimiles ; 30cmOther title:
  • استخدام المغناطيس الدائم الكهربى لتنظيم توليد قطرات موائع دقيقة [Added title page title]
Subject(s): Online resources: Available additional physical forms:
  • Issued also as CD
Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: This thesis introduces a novel method of active magnetic control of microdroplets inside ferrofluid-based microfluidic devices. In this work, a miniature electrop-ermanent magnet (EPM) is integrated with a polydimethylsiloxane (PDMS) microfluidic chip to achieve on-demand active control over the size of micro- droplets generated by a cross-junction microchannel. Moreover, on-demand size-based magnetic droplet sorting was demonstrated by coupling the EPM with conventional permanent magnets. This research proves that EPM is a capable magnetic actuator for active control inside ferrofluid-based microfluidic chips, which may well open the door to new applications in the field of microfluidics
