[求助] 请教大家传感器检测的灵敏度如何计算？

the sensor exhibited a linear response to glucose in the concentration range of 0.1 微摩 to 1.3 mM, with the regression equation of I (mA)
= 2.756 + 64.43c (mM) (R2= 0.9986). The sensitivity of this nonenzymatic glucose sensor was 911.96 mA mM-1 cm-2, and the detection limit was calculated to be 47 nM (at a signal-tonoise ratio of 3),

这里面的909.1 毫安每毫摩尔每平方厘米怎么计算出来的？请详细说明，谢谢
