Gels and hydrogels articles from across Nature Portfolio

Gels are materials composed of a three-dimensional crosslinked polymer or colloidal network immersed in a fluid. They are usually soft and weak, but can be made hard and tough. Hydrogels are gels that have water as their main constituent.

    Three-dimensional printing of hydrogels loaded with fungal mycelium can produce living materials with unique adaptive properties in shapes that are relevant for engineering applications. The metabolic activity of the living mycelial network allows the printed structure to grow autonomously and self-regenerate when it is provided with nutrients in water.
