Abstract:
1. A capillary tube for electrophoresis, the capillary tube having an inner surface and an outer surface, at least a portion of the inner surface coated with a first polymer layer, the first polymer layer comprising a plurality of polymer groups comprising (CH 2 CH 2 NH) x attached by a first linker group to a first anchor group, the first anchor group being covalently bonded to the inner surface of the capillary, the inner surface of the capillary further comprising a second polymer layer covalently bonded to the first polymer layer, the second polymer layer comprising a plurality of polymer groups comprising (CH 2 CH 2 NH) x attached by a second linker group to a second anchor group where x is an integer independently selected for individual polymer groups within the first or second layer, and the second anchor group being covalently bonded to a first anchor group of a polymer group from the first polymer layer.
