Single-molecule imaging and single-molecule manipulation techniques have been investigated to analyze various biological phenomena and information. In particular, direct observation of fluorescent-labeled single DNA molecules can be used for mapping, or for investigations on interactions with proteins and dynamics of biomacromolecules. For these purposes, single-molecule DNA manipulation is also a crucial technique. Because the form of DNA molecules always changes in solution by Brownian motion, a “physical form control” technique is required to analyze individual DNA molecules. For example, fluid flow, moving meniscus, optical trapping, or electric force can be used. At the same time, miniaturized chemical reaction systems such as micro total analysis systems (micro-TAS) have been actively studied in recent years. Fluid control is one of the most important aspects of microchannel networks, and various types of micropumps that can be integrated on a chip have been proposed. In addition, W/O emulsion system has attracted attention as a tool for miniaturized chemical reaction. In this system, each droplet is served as a micro-reactor containing different materials. It has been applied in combinatorial chemistries, for example, direct evolution of protein from gene library. In addition, when small amount of substrates such as single molecule are encapsulated in the droplets, effective concentration of the substrates can be increased, resulting in increased efficiency of chemical reactions. For example, single molecule polymerase chain reaction (PCR) was achieved using W/O emulsion, whereas conventional PCR did not succeed.

Some of those techniques developed in our laboratory will be presented in this lecture.
