This report outlines research, supported by a Kansai University special fund (2004). Collecting blood and sending it to a given destination is inevitable in micro-TAS application for the purpose of this research. Development of a micro-needle made of biodegradable polymer and a method for collecting blood with this micro-needle, evaluation of bloodstream characteristics in a micro-channel, and development of supporting technology for collecting and analyzing blood are discussed in this paper. In each case, successful new technologies were developed
