Abstract
We have developed a semi-automatic analysis system for detection of ultra trace amount of dioxin. The system has a label-free immunoassay chip which was reported in our previous paper. Sequence of all the reagents handling procedures, which includes sample injection, sensor calibration and regeneration, was automatically carried out by a micro volume liquid handling module. We also report improvement of the sensitivity of our sensor chip. Copyright © 2005 by the Transducer Research Foundation, Inc.
