Novel nanoparticles offer   the possibility of   significant improvement in separations.   Organic monoliths provide an opportunity for efficient separations or as a support for solid phase chemistry.   A method for the rapid, direct incorporation of nanoparticles functionalized with bioactive molecules can be complicated by the high temperatures associated with the classic thermal polymerization of organic monoliths.  Additionally, classic thermal polymerization of organic monoliths requires a significant amount of time.  We have developed a visible light cured organic monolith system that can be formed at room temperature on the timescale of minutes.  The conversion of the vinyl groups in the organic monoliths by visible light curing in �microcolumns� and microfluidic devices has been monitored by IR spectroscopy and confocal laser Raman microscopy, respectively.  Current efforts focus on the comparison of separations by this new method relative to classic thermal systems and the effect of embedded nanoparticles on targeted separations.
