Claims14
A test device for analyzing a sample, comprising:
- At least one nonporous surface coated with a coating comprising a mixture of an amine functional polymer and KOK.
A composition, comprising:
- an amine functional polymer;
- and
- KOK.
A method of improving hydrophilicity of a test device having at least
- one surface intended to contact and manipulate fluids, comprising the steps of:
- combining an amine functional polymer and KOK to form a combination;
- and
- applying said combination to at least a portion of at least one of said at least one surface of said test device.
