(A) Micrograph of a 2% hematocrit RBC solution flowing on-chip in Tris/Ringers buffer at 1.5 μL min⁻¹ adjacent to Tris/Ringers buffer with 30 mM SDS flowing at 2.5 μL min⁻¹ (taken with a 4x objective). (B) Amperometric data from RBCs using the on-chip injection setup. Buffer blanks were achieved by injecting Tris/Ringers buffer into the lysis channel containing Tris/Ringers buffer and 30 mM SDS. Non-lysis data was accomplished by adding cells to the Tris/Ringer buffer solution that was being injected and removing SDS from the lysis channel. Lysed cell data was obtained using the experimental conditions detailed in (A).
