Journal of Photopolymer Science and Technology 35(2) 147-151 2022年6月 査読有りMixing is difficult in microfluidic devices due to the low Reynolds’ number. We proposed and demonstrated a surface-acoustic-wave (SAW)-based microfluidic system which can control the temperature by mounting a heater. This device has a hollow cylindrical reservoir made of resin on a piezoelectric substrate (LiNbO3), and the solution can be rotated by injecting SAWs from both sides, which are shifted parallel to the central axis of the reservoir. 0.75 W of power was supplied to the IDT to generate SAWs, and the temperature rise of the liquid was measured with a thermographic camera when 0 to 0.55 W of power was supplied to the heater. As a result, by mounting the heater on the SAW actuator, it was possible to uniformly raise the temperature of a 40 µL micro-liquid by 8 to 40 °C in about 80 seconds, demonstrating the usefulness of this heater-mounted SAW agitation device.

Proceedings of the 16th International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2012 1192-1194 2012年1月1日We developed an automatic analytical system for the determination of an endocrine disrupting chemical, nonylphenol (NP), which employs a competitive Enzyme-Linked ImmunoSorbent Assay (ELISA) using a novel antigen-bound microfilter. The filter was set in a unique 3-dimensional microreactor, and all the fluidic processes for the reaction and detection were automatically performed according to a PC program in the system. By using this system, we obtained a negative standard curve, of which NP concentration range (0.01-0.40 μg/L) was much lower than the quantitative limit (5 μg/L) of a conventional ELISA kit for NP measurement. The coefficients of the variation were comparable to those of commercial products.

14th International Conference on Miniaturized Systems for Chemistry and Life Sciences 2010, MicroTAS 2010 3 1475-1477 2010年12月1日This paper reports a new type of lab-on-a-CD device with three-dimensional microchannel networks and vertical capillary bundle structures. The device consist of the multiple lab-on-a-CD chips with conventional planer microchannels and vertical microchannels which constructred on the disks made of poly-dimethylsiloxane (PDMS) and poly-methylmethacrilrate (PMMA). Three dimensioanl liquid transportation through vertical capillary bundle structure is suggested by computational fluid dynamics and it is successfully demonstrated by using fabricated chips. Detection of im-munogroblin G(IgG) from mouse is successfully demonstarated in the three-dimensional devices and it is notable that the result suggests quite high-sensitive implying detection limit down to few ng/ml by primitive result.

14th International Conference on Miniaturized Systems for Chemistry and Life Sciences 2010, MicroTAS 2010 1 345-347 2010年12月1日This paper presents high-sensitivity detection of poly-chrolinatedbiphnenil in three-dimensional lab-on-a-CD, which consist of multiple disks with three-dimensional microchannel networks. To perform the automatic sequencing of competitive protocol, capillary barrier type passive valves with vertically embedded capillary valve is designed and fabricated. Even it has three dimensional microchannel network, the performance and reliability of the device for the automatic liquid sequencing is indeed good. Finally we successfully demonstrated the detection of poly-chrolinatedbiphenil. It is notable that the reproducibility of the detection is strongly depending on the quality of scaffold and it is suggested that detection with concentration of sample down to 0.01ng/ml is possible.

環境技術 23(9) 544-548 1994年7月銅-DDTC錯体と共沈したのち, 酢酸エチルに溶解させる前濃縮法を用いて, 水中の微量のセレンを黒鉛炉原子吸光により分析する方法について検討した.4gの臭化カリウムを加えた検水100mlを0.75N塩酸酸性にし, オートクレープ (121℃, 20min) 中で加熱後, 室温まで冷却する.10%酢酸ナトリウム緩衝液5ml及び2.4mgのCu (II) を添加し, pHを3.5に調整したのち2%DDTC溶液10mlを添加してセレンを共沈させた.メンブランフィルターでろ過し, 25mlの酢酸エチルに沈殿を溶解させた後, 黒鉛炉原子吸光分析を行った.本方法の検出限界は47ng, 定量下限は157ngであった.本法を工場排水中のセレンの分析に適用した結果, JIS法による結果とよく一致した.
