Advanced Biomicrofluidics Support (ABS) at LiMe
The Shintaku Lab helps clinical medicine, basic life sciences, and engineering researchers solve their research problems by leveraging our microfluidics expertise.
We share our facilities for microfabrication, optical microscopy, and molecular biology with academic researchers. Here are some examples of sharing devices.

-Bright-field imaging (565 nm)
-Epi-fluorescence microscopy (Ex. 365, 455, 470, 565, 625 nm; Camera: Andor Sona)
-Confocal microscopy (spinning disc type, CSU-X1; Ex. 405, 488, 561, 640 nm; Camera: Andor iXon)
-XYZ stage
-Stage top incubator (CO2, humidified)
-Software: micro-manager
-Bright-field imaging (565 nm)
-Epi-fluorescence microscopy (Ex. (365, 470, 565, 625 nm))
-Camera: ORCA-Flash2.8

Electrokinetics
We have expertise in developing electrokinetic approaches (Shintaku et al. Anal Chem 2014, Abdelmoez et al. Anal Chem 2020) to manipulate cells and biomolecules. We have various voltage supplies such as High voltage sequencers (LabSmith), Source meters (Keithley), and in-house devices.
We support flow diagnosis with particle image velocimetry (PIV) and particle tracking velocimetry (PTV) (Shintaku et al. Angew Chem 2014, JFST 2009).
