Abstract

Crosslinked fluorocarbon surface coating, kits therefor, microfluidic devices having crosslinked fluoropolymer surface coatings, and methods of use for droplet generation are provided. The kits, devices, and their methods have a droplet source region that is coated with a crosslinked fluoropolymer surface coating produced by the reaction of a fluorocarbon silane and a fluorocarbon polyol.

Claims (19)

1 . A microfluidic device comprising:

a first channel or region being coated with a crosslinked fluorocarbon surface coating and having a first depth, a first width, a first proximal end, and a first distal end,

wherein the crosslinked fluorocarbon surface coating is produced by the reaction of a fluorocarbon silane and a fluorocarbon polyol,

wherein the fluorocarbon polyol is a compound of Formula V:

wherein:

V is —(CZ 2 ) n′ —C 1-15 perfluoroalkylene-(CZ 2 ) n′ — or —(CZ 2 ) n′ —(C 1-15 heterofluoroalkylene) n′ —(CZ 2 ) n′ —, wherein each Z is independently H, F, or C 1-6 perfluoroalkyl and each n′ is independently 1, 2, 3, 4, 5, 6 or 7.

2 . The device of claim 1 , wherein V is —(CZ 2 ) n′ —C 1-15 perfluoroalkylene-(CZ 2 ) n′ —.

3 . The device of claim 1 , wherein V is —(CZ 2 ) n′ —(C 1-15 heterofluoroalkylene) n′ -(CZ 2 ) n′ —.

4 . The device of claim 1 , wherein V has the structure of Formula VI:

wherein each n is independently 0, 1, 2, 3, 4, 5, 6, or 7, and m is 1, 2, 3, 4, 5, or 6.

5 . The device of claim 1 , wherein the fluorocarbon silane has the structure of Formula II:

wherein each n is independently 1, 2, 3, 4, 5, 6, or 7; and

m is 1, 2, 3, 4, 5, or 6.

6 . A microfluidic device comprising:

a first channel or region being coated with a crosslinked fluorocarbon surface coating and having a first depth, a first width, a first proximal end, and a first distal end,

wherein the crosslinked fluorocarbon surface coating is produced by the reaction of a fluorocarbon silane and a fluorocarbon polyol,

wherein the fluorocarbon silane has the structure of Formula II:

wherein each n is independently 1, 2, 3, 4, 5, 6, or 7; and
