The present disclosure relates to an ingestible device for sampling of the gastrointestinal tract. In particular, the device comprises an oral delivery capsule comprising a container having on the inside a hydrogel pre-polymer. The hydrogel prepolymer is capable of polymerising in situ, such as within the gastrointestinal tract, thereby collecting a sample of the gastrointestinal lumen by absorbing the lumen and its contents into the formed hydrogel.
