Highly proliferative cancer cells over express molecular markers such as epidermal growth factor receptor (EGFR). When specifically targeted gold nanoparticles bind to EGFR they tend to cluster on the cell membrane leading to an optical red-shift in the plasmon resonance frequency and an increase in absorption in the red region. These changes in optical properties provide the opportunity for photoacoustic...
Laser-induced fluorescence spectroscopy (LIF) and Raman spectrum of serum for detection of colon cancer and rectum cancer were investigated in this paper. The aim of this study was that using Raman spectrum and LIF analysis the serum of colon cancer and rectum cancer for found the difference compared to normal, the difference was found. For example: the peaks intensity and red shift are both different...
Laser-induced fluorescence and Raman spectroscopy of serum for detect colon cancer was investigated in this paper. The difference to serum spectrum was discovered. Three Raman peaks were consistently observed from normal blood serum emission using 488.0 nm and 514.5 nm excitation of an Ar-ion laser. While no Raman peak or slight Raman peaks were detected from colon cancer's cases. In addition, the...
Laser-induced fluorescence (LIF) and Raman spectra were measured from normal and tumorous human serum in an attempt to discover some values useful in discrimination between normal and tumorous cases. Red shift of fluorescence peak and decrease of fluorescence intensity were observed after samples radiated by laser. According to one thousand twenty-two samples' spectra, three parameters alpha, beta...
Laser-induced fluorescence spectroscopy (LIF) and Raman spectrum of serum for diagnosis of rectum cancer were investigated by criteria of three parametric modes in this paper. The aim of this study was in an attempt to find the difference normal and rectum cancer cases, therefore 89 rectum cancer samples were measured using fluorescence and Raman spectrum. The experimental result showed that there...
