摘要：
Various miniaturized and integrated in situ devices for biological and chemical oceanography have been developed in our research group. The devices targeted to analyze microbial gene, heavy metal ion (manganese: Mn2+) concentration and pH of seawater are evaluated and presented here. Flow-through PCR (polymerase chain reaction) can be performed with the microbial gene analysis device with integrated heating and pumping system. Mn2+ ion concentration is quantified by applying chemiluminescence reaction by the heavy metal ion analysis device. Micropumps are integrated to develop well-integrated pH measurement device. All devices are based on PDMS (polydimethylsiloxane) microchannel chip fabricated with conventional molding method.
