Manipulating fungal growth in engineered living materials through precise deposition of nutrients

One main challenge of emerging fungal-based engineered living materials (ELMs) lies in achieving localized multi-material properties in these structures. Although three-dimensional (3D) printing can efficiently vary local composition and properties, it has not yet been demonstrated in fungal-based E...
