Carbon nanotubes-modified poly-high internal phase emulsions for pharmaceuticals pre-concentration and determination

This paper deals with the preparation of new composites between polymerized/crosslinked high internal phase emulsions (polyHIPEs) and carbon nanotubes (CNTs), specifically designed for pharmaceutical analytical applications. While the composition of the polyHIPEs was maintained constant, the amount of CNTs was varied from 0.5% to 1% w/v. As proof-of-concept, the materials were tested for solid-phase extraction. Three drugs with different...
