Abstract: The present disclosure relates a method of fabricating a literal flow immunoassay (LFIA) for the diagnosis of diseases, including COVID-19. The present disclosure further relates to a fusion-epitopes peptide that can be used in the LFIA test to improve sensitivity, specificity and accuracy of the test.

Abstract: A modified approach for coral restoration by merging 3D printing and molding techniques is presented. This is achieved by 3D scanning live coral specimens, retrieved from sea dives, to obtain a CAD model of the complete coral 3D construction with complex geometries. Select areas of the model are flattened to create a 2D base for micro-fragment adhesion. From the CAD models, disclosed embodiments propose two methods of fabrication. Method A consists of 3D printing the CAD models with commercial thermoplastic materials to create a negative mold, subsequently loaded with synthesized Calcium Carbonate Photoinitiated (CCP) ink to form an eco-friendly coral skeleton. Method B uses syringe-based extrusion 3D printing to directly print a coral skeleton with CCP ink. Both methods are evaluated as a combined proof-of-concept process, 3D CoraPrint, for coral gardening and restoration and providing details required for mimicking coral and bone 3D structures for implantation in bone grafting applications.

Abstract: Described is a biomaterial/carbonate-based ink that comprises a biopolymer-based mixture and bioceramics. The photo- and ionic crosslinkable biopolymer mixture comprises polysaccharide and gelatin-based materials. The bioceramics comprises an apatite and a carbonate. The biopolymer-based mixture is mixed with the bioceramics to form the ink. The ink is capable of being applied under wet or dry conditions. The wet condition is seawater or water or other aqueous solution. The ink is capable to instantly get solidified, when UV or blue light is applied in the presence of the ionic components found in seawater. After photo- or ionic crosslinking, this ink is stable for months.

Abstract: Embodiments of the present disclosure describe a method of synthesizing a polymer comprising contacting a first monomer and an organolithium initiator in a nonpolar solvent and adding a promoter to the nonpolar solvent to polymerize the first monomer. Embodiments of the present disclosure further describe a method of synthesizing a polymer comprising contacting a first monomer and an organolithium initiator in a nonpolar solvent, adding a promoter to the nonpolar solvent to polymerize the first monomer, and adding a second monomer to the nonpolar solvent to polymerize the second monomer.
