We describe a series of new materials for high performance liquid chromatography (HPLC) and thin layer chromatography (TLC). In particular, new pellicular particles for HPLC are prepared by the layer-by-layer deposition of an amine-containing polymer and nanodiamond onto inert spheres. Separations of analytes showing more than 100,000 N/m have been seen. These materials seem to show excellent stability at high temperatures and extremes of pH. New materials for TLC were prepared by silicon infiltration of patterned carbon nanotube forests. Separations on these plates show 125,000 - 225,000 N/m, and are accomplished in only a fraction of the time of commercial plates.
