Mussel-inspired nanofibrous sheet for suture-less stomach incision surgery

We report a dopamine-based crosslinker-conjugated gelatin/polycaprolactone nanofibrous sheet. The nanosheet was then employed to treat stomach incisions without sutures during surgery. The mussel-inspired nanosheets, combining the advantages adhesion and tissue repair, show promise for use in treatments of fragile tissues and to avoid suture-caused stress concentration.
