DEVICE FOR MEASURING EXTRACELLULAR POTENTIAL AND METHOD OF MANUFACTURING DEVICE |
摘要 |
A device for measuring an extracellular potential of a test cell includes a substrate having a well formed in a first surface thereof and a first trap hole formed therein. The well has a bottom. The first trap hole includes a first opening formed in the bottom of the well and extending toward a second face of the substrate, a first hollow section communicating with the first opening via a first connecting portion, and a second opening extending reaching the second surface and communicating with the first hollow section via a second connecting portion. The first connecting portion has a diameter smaller than a maximum diameter of the first hollow section, greater than a diameter of the second connecting portion, and smaller than a diameter of the test cell. The device can retain the test cell securely and accept chemicals and the test cell to be put into the device easily.
