网页2015年6月22日 · forming microwave Raman heterodyne spectroscopy in Er:YSO. Raman heterodyne spectroscopy with radio fre-quency (ca. 0-200MHz) is a commonly used technique for nuclear spins in rare earth dopants [35{39]. It has also been demonstrated in the microwave regime in ruby [40, 41] and metalloprotiens [42]. These systems, how-
Detection of ER stress in vivo by Raman spectroscopy
网页2011年2月4日 · Here, we report on a method of detecting ER stress in vivo by Raman spectroscopy. Our experiments revealed that two specific Raman bands were reduced in both cultured cells and animal tissues in an ER stress dependent manner. This suggests that Raman spectroscopy could be a useful tool to detect …
