In this study, a novel cell assay is proposed, in which the chemical imaging sensor operated in SPIM mode is applied to monitor the recovery of defects in a cell layer brought into proximity of the sensing surface. A reduced impedance at a defect formed artificially in a cell layer was successfully visualized in a photocurrent image. The cell layer was cultured over two weeks, during which the temporal change of the photocurrent distribution corresponding to the recovery of the defect was observed.}, language = {de} } @article{MiyamotoYoshidaSakaietal.2011, author = {Miyamoto, Ko-ichiro and Yoshida, Midori and Sakai, Taito and Matsuzaka, Atsushi and Wagner, Torsten and Kanoh, Sanoh and Yoshinobu, Tatsuo and Sch{\"o}ning, Michael Josef}, title = {Differential setup of light-addressable potentiometric sensor with an enzyme reactor in a flow channel}, series = {Japanese Journal of Applied Physics. 50 (2011)}, journal = {Japanese Journal of Applied Physics. 50 (2011)}, publisher = {Japan Society of Applied Physics}, address = {Bristol}, isbn = {0021-4922}, pages = {04DL08-1 -- 04DL08-5}, year = {2011}, language = {en} } @article{MiyamotoWagnerYoshinobuetal.2011, author = {Miyamoto, Ko-ichiro and Wagner, Torsten and Yoshinobu, Tatsuo and Kanoh, Shin`ichiro and Sch{\"o}ning, Michael Josef}, title = {Phase-mode LAPS and its application to chemical imaging}, series = {Sensors and Actuators B: Chemical. 154 (2011), H. 1}, journal = {Sensors and Actuators B: Chemical. 154 (2011), H. 1}, publisher = {Elsevier}, address = {Amsterdam}, isbn = {1873-3077}, pages = {28 -- 32}, year = {2011}, language = {en} } @article{MiyamotoWagnerYoshinobuetal.2011, author = {Miyamoto, Ko-ichiro and Wagner, Torsten and Yoshinobu, Tatsuo and Kanoh, Shin`ichiro and Sch{\"o}ning, Michael Josef}, title = {Phase-mode operation of FDM-LAPS}, series = {Sensor letters}, volume = {9}, journal = {Sensor letters}, number = {2}, publisher = {American Scientific Publishers}, address = {Stevenson Ranch, Calif.}, isbn = {1546-1971}, pages = {691 -- 694}, year = {2011}, language = {en} } @article{MiyamotoWagnerMimuraetal.2011, author = {Miyamoto, Ko-ichiro and Wagner, Torsten and Mimura, Shuhei and Kanoh, Shin{\´i}chiro and Yoshinobu, Tatsuo and Sch{\"o}ning, Michael Josef}, title = {Constant-phase-mode operation of the light-addressable potentiometric sensor}, series = {Sensors and Actuators B: Chemical. 154 (2011), H. 2}, journal = {Sensors and Actuators B: Chemical. 154 (2011), H. 2}, publisher = {Elsevier}, address = {Amsterdam}, isbn = {1873-3077}, pages = {119 -- 123}, year = {2011}, language = {en} } @article{MiyamotoWagnerMimuraetal.2009, author = {Miyamoto, Ko-ichiro and Wagner, Torsten and Mimura, Shuhei and Kanoh, Shin`ichiro and Yoshinobu, Tatsuo and Sch{\"o}ning, Michael Josef}, title = {Constant-phase-mode operation of the light-addressable potentiometric sensor}, series = {Procedia Chemistry. 1 (2009), H. 1}, journal = {Procedia Chemistry. 1 (2009), H. 1}, publisher = {Elsevier}, address = {Amsterdam}, isbn = {1876-6196}, pages = {1487 -- 1490}, year = {2009}, language = {en} } @article{MiyamotoSugawaraKanohetal.2010, author = {Miyamoto, Ko-ichiro and Sugawara, Yuri and Kanoh, Shin´ichiro and Yoshinobu, Tatsuo and Wagner, Torsten and Sch{\"o}ning, Michael Josef}, title = {Image correction method for the chemical imaging sensor}, series = {Sensors and Actuators B: Chemical. 144 (2010), H. 2}, journal = {Sensors and Actuators B: Chemical. 144 (2010), H. 2}, pages = {344 -- 348}, year = {2010}, language = {en} } @article{MiyamotoKanekoMatsuoetal.2012, author = {Miyamoto, Ko-ichiro and Kaneko, Kazumi and Matsuo, Akira and Wagner, Torsten and Kanoh, Shin{\´i}chiro and Sch{\"o}ning, Michael Josef and Yoshinobu, Tatsuo}, title = {Miniaturized chemical imaging sensor system using an OLED display panel}, series = {Sensors and Actuators B: Chemical}, volume = {170}, journal = {Sensors and Actuators B: Chemical}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0925-4005}, doi = {10.1016/j.snb.2011.02.029}, pages = {82 -- 87}, year = {2012}, abstract = {The chemical imaging sensor is a semiconductor-based chemical sensor that can visualize the two-dimensional distribution of specific ions or molecules in the solution.

A microfluidic channel was constructed on the sensor surface of the light-addressable potentiometric sensor (LAPS), on which the ion concentrations could be measured in parallel at up to 64 points illuminated by optical fibers. The temporal change of pH distribution inside the microfluidic channel was recorded at a maximum rate of 100 frames per second (fps). The high frame rate allowed visualization of moving interfaces and plugs in the channel even at a flow velocity of 111 mm/s, which suggests the feasibility of plug-based microfluidic devices for flow-injection analysis (FIA).}, language = {en} }
