Time optimization of intratumoral injection of ACG hydrogel in mice. (A) Digital photographs of tumor color change derived from the reaction of ACG hydrogel with tumor during 12 h. (B) In vivo imaging of tumor fluorescence signal change derived from the reaction of ACG hydrogel with tumor during 12 h. (C) The quantitative analysis of fluorescent counts of tumor sites in (B) is shown as means ± SD, n = 5. (D) Blue tumors exfoliated at 12 h after intratumoral injection of ACG hydrogel. Up: color digital photograph. Middle: fluorescence photo. Down: overlay of grey photo and fluorescence photo.
