Figure 1. RTS and microfluidic chip fabrication description.

(a) Different steps of the RTS fabrication. (b) SEM pictures of the RTS after all steps of fabrication have been completed and its dimensions. (c) Fabrication steps of the microfluidic chip. (d) Illustration of the actuation of RTS by a homogenous magnetic field. (e) Picture of the final chip. This field is produced by 3 orthogonal pairs of Helmholtz coils.
