Fig. 6From: In-Vivo fluorescent nanosensor implants based on hydrogel-encapsulation: investigating the inflammation and the foreign-body responseMasson’s Trichrome stained tissue samples imaged at 4x magnification. The progression of healing can be seen by observing the regions of blue, representing fibrous tissue, increasing from day 7 to day 28. Formulations 3–5 appear to have slightly more organized fibrous regions at day 7 compared to formulations 1 and 2, indicating faster healing with smaller pore sizes, as well as lower SWNT concentrations. The hydrogel itself or locations of the hydrogels are marked by arrowsBack to article page
