14.A more thorough discussion of the relative magnitude of the two effects in the transverse direction will be given elsewhere (E. Brunet, A. Ajdari, in preparation), but the point is clear in the lubrication limit (see Eq. A7 and the coefficients and in Ref. 13).

20.Aged PDMS possesses slightly lower surface mobility than the freshly oxidized PDMS. See Ref. 19 and G. Ocvirk, M. Munroe, T. Tang, R. Oleschuk, K. Westra, and D. J. Harrison, Electrophoresis 21, 107 (2000).
21.The reaction of carboxylate functionalized beads (suspension of 2% by weight) with amine-terminated PEG was done in phosphate buffer (200 mM, 8) using EDC(30 mg/mL)/NHS(5 mg/ml) coupling. First, 200 mg/mL) was allowed to react for 15 min, followed by three consecutive reactions with (4 mg/mL).
22.The system in Fig. 2 consists of a patterned active section of length and a passive unpatterned section of length assembled in series. The hydrodynamic resistances per unit length of these two sections are similar. We expect the velocities measured in the such system to be smaller by a factor of roughly than would be obtained in a fully patterned channel.
23.The proportionality constant between the secondary and primary flow rate is for
24.We estimate that at 100 V/cm in 1 mM NaCl solution, the average concentration of and in water at steady state is and respectively. These concentrations exceed the solubility limit of these gases in water, and thus can result in formation of bubbles.
25.The electrochemical reaction in the absence of electroactive species involves generation of ions at the anode and consumption of ions at the cathode
