Microfluidic capturing-dynamics of paramagnetic bead suspensions.
نویسندگان
چکیده
We study theoretically the capturing of paramagnetic beads by a magnetic field gradient in a microfluidic channel treating the beads as a continuum. Bead motion is affected by both fluidic and magnetic forces. The transfer of momentum from beads to the fluid creates an effective bead-bead interaction that greatly aids capturing. We demonstrate that for a given inlet flow speed a critical density of beads exists above which complete capturing takes place.

Microfluidic Bead Suspension Hopper
Many high-throughput analytical platforms, from next-generation DNA sequencing to drug discovery, rely on beads as carriers of molecular diversity. Microfluidic systems are ideally suited to handle and analyze such bead libraries with high precision and at minute volume scales; however, the challenge of introducing bead suspensions into devices before they sediment usually confounds microfluidi...
متن کاملMicrofluidic immunomagnetic multi-target sorting--a model for controlling deflection of paramagnetic beads.
We describe a microfluidic system that uses a magnetic field to sort paramagnetic beads by deflecting them in the direction normal to the flow. In the experiments we systematically study the dependence of the beads' deflection on bead size and susceptibility, magnet strength, fluid speed and viscosity, and device geometry. We also develop a design parameter that can aid in the design of microfl...
متن کاملMicrobeads for Sampling and Mixing in a Complex Sample
This paper presents work on the development of a microfluidic device using super-paramagnetic beads for sampling and mixing. The beads are manipulated via an external rotating permanent magnet in a microfluidic channel. Efficient mixing is achieved in a short distance with this method. Modeling shows the variables which influence the mixing are flow rate, bead rotation speed and the bead number...

This work presents the investigation of hydrodynamic filling of beads into flat microfluidic devices. A periodical hexagonal monolayer as aggregation pattern is favorable for parallel optical detection. Several microfluidic devices for bead-based analyses were designed. Each microfluidic device consists of one inlet channel, one flat aggregation chamber for the beads and several outlet channels...
متن کاملGuided self-assembly of magnetic beads for biomedical applications
Micromagnetic beads are widely used in biomedical applications for cell separation, drug delivery, and hypothermia cancer treatment. Here we propose to use self-organized magnetic bead structures which accumulate on fixed magnetic seeding points to isolate circulating tumor cells. The analysis of circulating tumor cells is an emerging tool for cancer biology research and clinical cancer managem...
