[Differentiating gastric cancer cell from normal cell by laser Raman spectrum].
The gastric cancer cell and normal cell were comparatively detected by means of laser Raman spectrum in the present paper. The special Raman spectrum wave crest of gastric cancer cell was inquired. It was found that the special Raman spectrum wave crest of gastric cancer cell differs from the one of normal cell. After the sample at concentration of 1.25 x 10(5) individual x mL(-1) was cultivated for several days, a few special Raman spectrum wave crests of sample at 583, 633 and 656 nm respectively were detected. This is a few new special Raman spectrum wave crests rarely reported. Whether at the special Raman spectrum wave crests or at the same several Raman spectrum wave crests 674, 707, 773 and 799 nm for both canner cell and normal cell, the Raman spectrum intensity increases with the cancer cell concentration. As a result, the laser Raman spectrum analyse is considered truly a kind of rapid and effectual method to check cancer cell.
