Guiding of Liquids via Patterned Surface Coatings to Facilitate Solid-phase Extraction in Two-phase Flow
نویسندگان
چکیده
We present a concept for solid phase extraction of compounds from reactions contained in the dispersed phase of twophase flow based on the manipulation of liquids via patterned surface chemistry. Approaches to guiding of liquids via patterned surface coatings have been proposed by several groups [1-3]. However, few practical applications of such approaches have been reported to date. We demonstrate a simple and efficient method for extraction of compounds from nanoliter-sized liquid plugs using magnetic beads as carrier.

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...
