| Research Abstract |
Bonding of two substrates is key technology for development of new micro-machine. Until now, a technique to fabricate small structure have been developed and established by a lot of researchers. However, traditional joining techniques of two substrate with small structure have a lot of problem, and development of new joining technique has been hoped. In this research project, we study some joining methods in normal condition(temperature and pressure). Firstly, we tried the joining by using electrostatic force of poly-ion layer on glass slides. It was found that the joining could be achieved by applying an electrical potential above 500 V, and the joining force was 1.36 kgf cm^<-2>. Next, a polymerization reaction of silage-coupling reagent was employed for the joining of glass substrates. By spreading the silane-coupling reagent between two glass substrates, the joining could be achieved without heating and applying electrical potential and the bonding force was 5.6 kgf cm^<-2>.. Moreover, it was confirmed that this technique could be applied for construction of micro-flow-channel without leak. Last, we studied the micro-flow-channel using polydimethylsiloxane(PDMS). Micro-channel was fabricated at PDMS substrate and then the substrate was covered by glass without any reagent for joining. As a result, water flow without leak was observed and it was confirmed that this technique could be applied for micro-electrode system. Therefore, we fabricated an arrayed micro-enzyme electrode on glass substrate, and developed enzyme flow sensor using PDMS micro-channel. This sensor showed good electrochemical response for glucose and lactate with high selectivity.
