- Microbial living materials promote coral larval settlement.

Low recruitment success on degraded reefs hampers coral sexual propagation and leads to reduced genetic diversity and impaired reef resilience. Here, we introduce a Bacterial Reef Ink (Brink) to assist in coral larval settlement. Brink is a photopolymerized living material that can be rapidly applied to restoration substrates and has been formulated to cultivate two settlement-inducing bacterial strains ( and ). Settlement assays performed with broadcast spawning () and brooding () Indo-Pacific corals showed that Brink-coated substrates increased settlement >5-fold compared with uncoated control substrates. Brink can be applied as a flat coating or patterned using light-assisted 3D bioprinting, enabling diverse applications in reef restoration and engineering. This approach demonstrates the potential of functional living materials to enhance coral ecosystem engineering and support coral reef rehabilitation.
