Single File Flow of Biomimetic Beads for Continuous SERS Recording in a Microfluidic Device

Figure 1

(a) Picture of the microfluidic device presenting inlets (1,2) and outlet (3). (b) Scheme of the microfluidic device: the carrier liquid (light blue) confines the inner fluid (green) that contains the PS beads (red spots). The scheme shows that the focusing is more efficient in the channel region (D) than in the chamber part (D′). P₁, P₂, and P₃ are the pressure corresponding to the inlets/outlet shown in (a).
