Caption : figure s2. the relative standard deviation (rsd) of acth levels, depicted in blue for the room temperature group and green for the 4°c group, was observed at the 4-hour, 8-hour, and 24-hour intervals. (rsd=δcacth/cacth(0), δcacth=cacth-cacth(0).cacth denotes the acth levels measured at the 4-hour, 8-hour, and 24-hour intervals, while cacth(0) refers to the baseline acth levels at the 0-hour mark.)

Caption : figure s3. (a) the atomic force microscopy (afm) image of a few-layer rgo connected to au electrodes, with lines 1, 2, and 3 representing the measurement paths. (b) the histogram depicts the depth analysis of the entire rgo region's thickness within the blue box in figure s3a. reveals the rgo sheet thickness. (c-e) height profiles along three measurement paths (1-3) on the afm image.
