摘要
We present a method that allows the on-demand release and mixing of zepto- to femtoliter volumes of solutions in the interior of vesicular nanoreactors. The reactors comprise a nested system of lipid vesicles, part of which release their cargo in the interior of the others during a thermotropic phase transition. The performance of individual reactors immobilized on glass is characterized using confocal microscopy and a fluorescent dye that reports dilution during the release. The results confirm the predicted temperature-induced response and reveal a release transition width of 3 °C with a half time of ∼1 min. Copyright © 2004 American Chemical Society.
