3D printed coral-like structures have proven capable of growing dense populations of microscopic algae which may lead to fore efficient bioreactors for producing algae-based biofuels.
The same technology could also help to repair and restore coral reefs.
The artificial coral skeleton was created with a combination of polymer gels and hydrogels infused with cellulose nanomaterials to mimic the optical properties of living coral.
The printed coral copies natural coral structure and light-harvesting properties thus creating an artificial host-microenvironment for living microalgae.
