A rapid trapping and detection method for clinical bacteria (Helicobacter pylori, H. pylori) analysis is designed and reported in this study. Different strain of H. pylori can be trapped in 3 dimension dielectrophoresis chip (DEP) under the condition of 20 mM PBS, voltage at 20 Vp-p and frequency at 300 kHz. H. pylori #238(Wild type) presents more and stronger functional group stretching and vibration...
In this paper, laser induced human serum Raman spectra of liver cancer are measured. The spectra in serum differences between normal people and liver cancer patients are analyzed. For the typical spectrum of normal serum, there are three sharp Raman peaks and relative intensity of Raman peaks excited by 514.5 nm is higher than that excited by 488.0 nm. However, for the Raman spectrum of liver cancer...
