The schematic representation illustrates the process of three-dimensional (3D) bioprinting and photocrosslinking a cell-laden scaffold based on poly(ethylene glycol) dimethacrylate (PEGDMA). In this study, PEGDMA was synthesized using a microwave-assisted synthesis method. The bioink comprised a mixture of PEGDMA-based polymer and murine preosteoblasts. The cell-laden PEGDMA-based scaffolds were then 3D bioprinted using an extrusion-based 3D printer. The scaffolds demonstrated over 80% cell viability over a 7-day study period.

By inspiration of the natural bone structure, a heterogeneous porous titanium scaffold was designed to mimic both the cortical and cancellous bone. The scaffold was fabricated by selective laser melting printing, and the finite element simulation was applied to evaluate the scaffold's mechanical properties. This customized 3D-printed heterogeneous porous titanium scaffold has potential in bone tissue engineering application.

Polymers play a pivotal role in ocular drug delivery, revolutionizing treatment approaches. These biomaterials enable controlled and sustained drug release at the targeted site, enhancing bioavailability and patient compliance. From nanosized particle-based formulations to in situ gelation mechanisms, polymers offer improved treatment options for a diversity of ocular diseases (Figure created using Microsoft Designer).

Innovative carbon-based conductive scaffolds hold promise in tissue engineering, providing structural support and electrical cues crucial for regenerating functional tissues.
