Abstract: A bioinspired suction device includes a radially symmetrical suction chamber formed from a first elastomer and having a skirt portion with a skirt diameter and a disc margin formed from a flexible flattened ring adhered to a lower surface of the skirt portion. The disc margin is formed from a second elastomer and has a disc diameter that extends beyond the skirt diameter. The second elastomer is a compliant material having a lower hardness and lower tensile strength than the first elastomer. Radial pads may extend from the disc margin, where each pad has elastomeric texture features formed on a pad contact surface.

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.
