Dear Colleagues:

Light-based bioprinting techniques have greatly revolutionized modern regenerative medical study with unprecedented breakthroughs. Their potential to fabricate deep scaffold vascular structures and cellular organization in the construct among others has recently gained prominence. The light-based bioprinting techniques’ dependency on light as stimuli for the polymerization of bioinks thus threw open novel designs of photo-responsive bioinks through photo-chemistry. This issue covers the recent advances in the fabrication of scaffolds to imitate the complexity of native tissues through the synthesis of photosensitive polymers and the development of light-based bioprinting techniques. These includes:

1.    Photochemistry, synthesis, and fabrication of photo-responsive biomaterials to serve as bioink for light-based bioprinters.

2.    New light-based bioprinting technologies.

3.    The applications of light-based bioprinting to tissue engineering, regenerative and developmental medicine, drug screening, and disease models.
