Formulated NapFFεKεK-OH hydrogel properties. (A) The assembled NapFFεKεK-OH hydrogels (0.5–2% w/v) were shown to be self-supporting. (B) Confocal microscopy of DPSCs 24 h after their encapsulation in 0.5–2% w/v NapFFεKεK-OH hydrogels, showed that cells were retained in 3D within the hydrogels. Cells were fixed and permeabilised within the hydrogel before staining of the encapsulated DPSC nuclei with DAPI. Images were captured using an SP8 Confocal Microscope. Scale bar: 100 µm.
