Miniaturization of laboratory procedures is opening new possibilities in medicine by allowing point of care diagnostics, precision medicine, novel therapeutics, reliable manufacturing of biologics, as well as applications that are likely unpredictable a priori. A fundamental challenge, however, is in the miniaturization of the test-tube. As compartments get smaller, surface effects begin to dominate over gravity and handling of fluids requires new strategies that take advantage of nanoscale effects. Biological systems provide a solution to this problem through the formation of fluid cellular and sub-cellular compartments defined by lipid bilayers as the boundaries. Inspired by this approach, Lenhert’s research in the last five years has focused on the formation of arrays of lipid droplets on surfaces in order to effectively miniaturize the test tube for high throughput screening of small molecule drugs and as nanostructured biosensor elements. Recent progress in the following areas will be presented: (1) lipid multilayer nanofabrication on surfaces, (2) drug screening microarrays for cell culture, and (3) the use of lipid nanostructures as sensor arrays and model membrane systems for testing hypotheses about how cells organize their molecules.
