Fig. 8.4 a Schematic of a microfluidic chip integrated with a WG for identifying the attractant that
induces Phormidium gliding, and b absorption spectra of water containing a BTB solution (green
line), water with a seedling root (yellow line), and carbonic water with varying CO 2 concentrations
(blue line: 10 ml CO 2 in 50 ml H 2 O, black line: 15 ml CO 2 in 50 ml H 2 O, red line: 25 ml CO 2 in
50 ml H 2 O) [22]
