DOCUMENT TYPE: Journal CA Section: 9 (Biochemical Methods) Section cross-reference(s): 7, 75 This manuscript describes the effect of interfacial tensions on three-phase liq.-liq.-liq. flow in microfluidic channels and the use of this flow to prevent microfluidic plugs from coalescing. One problem in using microfluidic plugs as microreactors is the coalescence of adjacent plugs caused by the relative motion of plugs during flow. Here, coalescence of reagent plugs was eliminated by using plugs of a third immiscible liq. as spacers to sep. adjacent reagent plugs. This work tested the requirements of interfacial tensions for plugs of a third liq. to be effective spacers. 647-42-7 and 56-33-7 which are cas registry numbers of chemicals are mentioned. Two candidates satisfying the requirements were identified, and one of these liqs. was used in the crystn. of protein human Tdp1 to demonstrate its compatibility with protein crystn. in plugs. This method for identifying immiscible liqs. for use as a spacer will also be useful for applications involving manipulation of large arrays of droplets in microfluidic channels. .
