Two-dimensional magnetic manipulation of microdroplets on a chip as a platform for bioanalytical applications

Martinus Gijs, Amar Rida, Caroline Vandevyver, Virendra Kumar Parashar, Ulrike Lehmann

Manipulating biological samples in microliter droplets has vast potential in molecular diagnostics. We present a system for the two-dimensional (2D) magnetic manipulation of aqueous droplets suspended in silicone oil as a platform for on-chip bioanalysis. ...

Droplet-Based DNA Purification in a Magnetic Lab-on-a-Chip

Martinus Gijs, Caroline Vandevyver, Virendra Kumar Parashar, Ulrike Lehmann

Merge, Mix, Split and Transport, these are the main manipulation steps used for on-chip droplet-based DNA purification (see figure). The system is able to extract genomic material from dilute cell samples by using the actuation of magnetic microparticles w ...

Two dimensional magnetic manipulation of microdroplets on a chip

Martinus Gijs, Virendra Kumar Parashar, Ulrike Lehmann

In this paper we describe the two-dimensional (2D) magnetic manipulation of aqueous droplets suspended in silicone oil over the chip surface. The magnetic actuation is based on the force imposed on superparamagnetic microparticles inside the droplets. Thes ...
