bit25007-sm-0001-SupFig-S1.tif2050KFigure S1. Procedure of bacteria chemotaxis assay using microfluidic chamber. (a) Fabricated microfluidic chamber of 200 µm width and 80 µm height, (b) PBS buffer (A- and B-INLET) and buffer containing a chemo-repellent/chemo-attractant (C-INLET) were loaded into the INLET reservoirs using a 19-gauge plastic needle. c: When the buffers flowed out to OUTLET, OUTLET reservoir was closed with blocked 19-gauge plastic needle, and (d) After 10 min, the chemical gradient was generated and maintained for over 80 min and the concentrated bacteria or bacteriobot solution was infused into the middle INLET (B-INLET).
