| We are developing a revolutionary new form of miniaturized liquid chromatography using Atomic Force Microscope (AFM) technology. Rapid nano-chromatography benefits a broad range of in situ planetary missions that include Europa, Titan, and Mars. The proposed system directly addresses the chemical analysis of ice and soil extracts. The new chromatographic concept uses the AFM tip-cantilever as a mechanism for shear driven pumping of fluids in micro-channels for chromatography. Shear driven pumping allows very high flow rates without the limitations of conventional pressure and electrically driven pumping. The AFMs ability to translate sub-femtoliter volumes of fluid also proves a mechanism for fluidic switching and sample injection. Our initial results demonstrate the feasibility of integrating AFM technology with microfluidic circuits and the potential for nanometer scale chromatography. The talk is an update on our recent work to develop AFM mediated nano-scale chromatography. |
