Table 1.

Eleven nanofiber sensor examples with reported lower limit of detection (LDL) and precision or relative standard deviation (RSD). LDL indicates the general sensitivity of the sensor. RSD is chosen to show the general consistency of the measured sample. The # will consistently be used for Table 2 and Table 3.
