Published in: Expert opinion on drug delivery (2024)
The fields of tissue engineering and regenerative medicine are evolving at a significant pace with researchers constantly focused on incorporating advanced manufacturing techniques for the development of versatile, complex, and biologically specific platforms. 3D bioprinted microneedles, fabricated using conventional 3D printing techniques, have resultantly provided an alternative to 2D bioscaffolds through the incorporation of biological materials within 3D constructs while providing further mechanical stability, increased bioactive permeation and improved innervation into surrounding tissues. This advancement therefore potentially allows for a more effective biomimetic construct with improved tissue-specific cellular growth for the enhanced treatment of physiological conditions requiring tissue regeneration and replacement.
