Abstract
An artificial structure for promoting microalgae growth includes a 3D-printed structure formed by positioning a printing surface on a movable stage of a 3D bioprinter in contact with a bio-ink that includes a mixture of a pre-polymer material with one or more of cellulose-derived nanocrystals (CNC), and microalgae cells. By projecting modulated light onto the printing surface while moving the stage, the bio-ink is progressively polymerized to define layers of an artificial coral structure with microalgae cells disposed thereon, where the artificial coral structure is configured to scatter light within the structure.
