Stimulus-sensitive hydrogels and their applications in chemical (micro)analysis

In this tutorial review the use of stimulus-sensitive hydrogels as sensors and actuators for (micro)analytical applications is discussed. The first part of the article is aimed at making the reader familiar with stimulus-sensitive hydrogels, their chemical composition and their chemo-physical behavior. The prior art in the field, that comprises a number of sensors ranging from metal ion-sensitive sensors to antigen-sensitive sensors and a few actuators, is also treated in this part. The second part of the article focusses on the use of stimulus-sensitive hydrogels for microsensors and microactuators as well as their application in micro total analysis systems. The benefits of stimulus-sensitive hydrogels, their miniaturisation and the use of 365 nm UV-photolithography as a fast economical manufacturing technique are discussed

A flow-through potentiometric sensor for an integrated microdialysis system

In this paper, the performance of a flow-through potentiometric sensor based on a semi-permeable dialysis tubing implemented in silicon, is presented. The sensor is designed as part of a lab-on-a-chip system and has been successfully incorporated into an integrated microdialysis system. Results of a potassium sensor, operating stand-alone, and as part of the integrated system are presented
