%0 Journal Article %T ¦Â3-Tripeptides Coassemble into Fluorescent Hydrogels for Serial Monitoring in Vivo %J - %D 2018 %R https://doi.org/10.1021/acsbiomaterials.8b01065 %X ¦Â3-peptides uniquely form shear thinning hydrogels which are proteolytically stable and biocompatible. Herein we describe the synthesis, material and optical characterization of a new class of fluorescently labeled hydrogelators based on a helical N-acetylated ¦Â3-peptide backbone. The resulting hydrogels were analyzed using fluorescence microscopy to confirm successful incorporation of the fluorophore within the fiber matrix without compromising the ¦Â3-peptide self-assembly. Serial, noninvasive conscious animal imaging was used to monitor the injected hydrogel, delivered via subcutaneous injection, while tracking their degradation patterns in real-time. The hydrogels demonstrated persistent, high-intensity fluorescence when monitored over a 14-day period %U https://pubs.acs.org/doi/10.1021/acsbiomaterials.8b01065
