| 中文摘要 | the effect of alcohol solution on single human red blood cells (rbcs) was investigated using near-infrared laser tweezers raman spectroscopy (ltrs). in our system, a low-power diode laser at 785 nm was applied for the trapping of a living cell and the excitation of its raman spectrum. such a design could simultaneously reduce the photo-damage to the cell and suppress the interference from the fluorescence on the raman signal. the denaturation process of single rbcs in 20% alcohol solution was investigated by detecting the time evolution of the raman spectra at the single-cell level. the vitality of rbcs was characterized by the raman band at 752 cm(-1), which corresponds to the porphyrin breathing mode. we found that the intensity of this band decreased by 34.1% over a period of 25 min after the administration of alcohol. in a further study of the dependence of denaturation on alcohol concentration, we discovered that the decrease in the intensity of the 752 cm(-1) band became more rapid and more prominent as the alcohol concentration increased. the present ltrs technique may have several potential applications in cell biology and medicine, including probing dynamic cellular processes at the single cell level and diagnosing cell disorders in real time. copyright (c) 2005 john wiley t sons, ltd. |
