Fluorescence imaging of an isolated brain by the in vivo imaging system. The brain of 0 h is a blank control. The blank brain of rats has a matrix fluorescence response at 492 nm, and the fluorescence images at each time are the fluorescence response after eliminating the blank interference. (a) Fluorescence response in isolated brains; (b)The trends of fluorescence response of the solution group and the in situ gel group; (c)The difference of fluorescence response between the solution group and the in situ gel group. (Error shown as one standard deviation of the mean, n = 5, * p < 0.05, ** p < 0.001, *** P < 0.0001).
