摘要:
Exposure to a static magnetic field changes the fluorescence intensity of a wide range of fluorophores, including small molecules (e.g., tryptophan), complex organizations of fluorophores (e.g., proteins), quantum dots, nanoparticles, and other materials. Different materials may experience different changes in fluorescence emission upon exposure to a magnetic field— for instance, some or all of a material's fluorescence emission spectrum may increase in amplitude or shift in wavelength. Different materials may also experience different changes in relaxation time, which is the time constant associated with fluorescence decay. These magnetically induced differences fluorescence emission spectra and decay can be used to identify, classify, or sort materials noninvasively.
摘要(中):
暴露于静态磁场会改变荧光团的荧光强度,包括小分子(如色氨酸),荧光团(如蛋白质),量子点,纳米颗粒和其他材料的复杂组织。 不同的材料在暴露于磁场时可能会发生荧光发射的不同变化 - 例如,材料的一些或全部荧光发射光谱可能会增加幅度或波长偏移。 不同的材料也可能经历不同的弛豫时间变化,这是与荧光衰变相关的时间常数。 这些磁诱导差异荧光发射光谱和衰变可用于非侵入性地识别,分类或分类材料。
