The accuracy of two classes of nanoscale thermometers is estimated in terms of size and system-dependent properties using the spin-boson model. We consider solid state thermometers, where the energy splitting is tuned by thermal properties of the material, and fluorescent organic thermometers, in which the fluorescence intensity depends on the thermal population of conformational states of the thermometer. The results of the theoretical model compare well with the accuracy reported for several nanothermometers that have been used to measure local temperature inside living cells.
利用自旋玻色子模型，根据尺寸和系统相关特性对两类纳米级温度计的精度进行了估计。我们考虑了固态温度计，其能量分裂由材料的热特性调节；以及荧光有机温度计，其中荧光强度取决于温度计构象状态的热布居。理论模型的结果与已用于测量活细胞内局部温度的几种纳米温度计所报告的精度吻合良好。
