- Abstract
We have successfully achieved terahertz imaging of cellulose acetate membrane electrophoresis of egg albumin using continuous-wave imaging at 0.189 THz. A sample holder has been devised that can eliminate the membrane crook generated in the drying process after electrophoresis. A probe has been also fabricated, which was assembled with a Schottky barrier diode detector to detect the terahertz signal. A higher spatial resolution of 0.3 mm was achieved, which is 6.83 times the 2.05-mm resolution without using the probe. Terahertz images of cellulose acetate membrane electrophoresis of egg albumin of 2 µl was obtained, in which the positions of protein were perfectly in accordance with the stained images. The technology can be used instead of the staining method for cellulose acetate membrane electrophoresis. © 2012 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
