Research output: Unpublished contribution to conferencePoster


Liquid Chromatography (LC) is one of the most applied analytical techniques used to process complex samples in the life sciences
and analytical chemistry. Up till now, the progress in LC has been realized by reducing the size of spherical particles, randomly
packed in columns, and concomitantly increasing the pressure. A more groundbreaking progress can be achieved by leaving the
randomly packed bed paradigm and using a layer-by-layer manufacturing strategy to position micrometer-sized spheres in openstructured
3D arrangements with nanometric tolerances. Each particle-layer is collected using pre-etched vacuum-driven, microstructured
collection and deposition tray, and arranged with an array of precisely positioned suction holes capable of reversibly
holding the particles.
This proposed nano-precision fabrication strategy is expected to deliver a disruptive gain in separation speed.
