An Integrated Microfluidic Device for the Preparation and Evaluation of Magneto-responsive Composite Particles
نویسندگان
چکیده
We present a microfluidic-based method allowing for the controlled production of lipid particles with encapsulated magnetic nanoparticles (MNPs). Within the same device, the magnetic properties of the composite particles are tested as they flow downstream. The effect of the fluid properties and flow parameters on the size of the microparticles containing MNPs is studied using standard flow visualization. The magnetic properties of the composite particles are characterized by studying their trajectory in a straight section of the channel, under a super-imposed magnetic field. Their deviation depends on their load, on the magnitude of the field, and on the flow conditions.
