a–d, Evolution of conductivity in the concentrate and diluate during fractionation of antibiotic and NaCl in the (a) ceftriaxone sodium/NaCl, (b) cefotaxime sodium/NaCl, (c) carbenicillin disodium/NaCl and (d) ampicillin sodium/NaCl mixed solutions, respectively, by electro-driven process using the NPM-6 membrane at a current of 0.5 A (inset: content of NaCl in both concentrate and diluate and content of antibiotic in the concentrate). e, Details of the MD simulation domain (note that water molecules are not shown in the simulation domain for clarity). f, Drift velocity of Na+, Cl− and ampicillin ions with samples collected at every 200 fs interval for the last 15 ns across three runs for MD system. The error bars represent the standard deviation from three simulation runs.
