Preface
Micro Total Analysis Systems 2000 (J..tTAS 2000) is the fourth international conference entirely dedicated to the newest scientific and technological developments in the field of miniaturized systems for (bio )chemical analysis and synthesis. Initiated in 1994 by Piet Bergveld and myself as an attempt to bring together in one workshop scientists with an analytical (bio )chemical background and microsystem researchers and engineers, the J..t T AS workshop series started in Enschede in 1994 with around 160 participants, began to grow in following meetings: Basel in 1996 (275 participants) and the very successful form er meeting in Banff in 1998 ( 420 participants ). These successes are a clear indication of the need for such a multidisciplinary meeting on the one hand, and perhaps, more important, an indication of the enormous commercial potential of "labs-on-a-chip", as such systems are frequently named. At the meeting of the steering committee during J..tTAS '98 in Banff, first of all it was decided to change the frequency of the meeting from biannual to annual via an interim period of three meetings spaced 18 months apart. Further, the decision was taken that quality rather than quantity would be the key-point for future ~TAS conferences, and that the single-session format would be maintained as much as possible. Given this fact, and the logistic constraints of the location at the University of Twente, for this meeting the program committee had to select 34 oral presentations and 100 posters out of over 230 submitted abstracts, implying an acceptance rate slightly below 60%. T ogether with the 12 excellent invited speakers, I believe that the program committee has realized a very high quality program, and I want to thank them all for their hard task ofreading through all the abstracts. Chapeau!
Compared to the earlier meetings there is one striking observation, which is that new trends appear to be impredictable! Array-systems, one of the highlights in Banff, have already entered the commercial domain, and research efforts seem to have diminished. Apart from genomic analysis there is now much focus on cell analysis. There is a lot of exciting research on centrifugal fluidic systems using plastic-CD devices as a disposable platform, not presented at the form er meeting. The merger of J.l T AS with microreaction devices into micro (bio )chemical systems seems to be an indication of a paradigm shift taking place not only in analytical or pharmaceutical chemistry, but in chemistry as a whole: why should one synthesize more than a couple of nanoliters of a certain compound if all necessary assays or screens can be made with that small amount? It is the information content that counts, and in that case miniaturization always pays off. Finally, it is amazing to see the innovation potential of the J..tTAS field: photoacoustic detection in microreactors, molecular emission detection on a chip, very high pressure microreactor devices and shear-flow driven Separations are just a couple of examples of the exciting novelties at this meeting.
This volume contains the manuscripts of all the presentations of j.tTAS 2000, starting with the oral presentations according to the conference program per day, followed by all of the related extended abstracts from the posters, arranged by topic as much as possible. In this way this book may serve the conference participants during the meeting and interested readers as textbook afterwards. Authors and subject indexes are added to facilitate consultation of references.

Finally, I would like to express my great gratitude to the local orgamzmg committee, Piet Bergveld, Juergen Brugger, Martin van Es, Han Gardeniers, Hermine Knol, Jose Nijhuis, Wouter Olthuis and Janny Spierenburg for their assistance and initiatives in organizing this meeting. Further, I would like to thank J ed Harrison and Andreas Manz for their helpful informal comments and suggestions, and the former MESA-director Jan Fluitman who brought up the suggestion to start this workshop series almost 7 years ago. But of course the most important contribution to the success of this meeting comes from you, the participants! I wish you lots of excitement at this meeting from the oral and poster presentations in addition to the invaluable personal contacts. I am fully convinced that this proceedings may serve as a reference work at least until the next 1.1.TAS meeting!
