LAP photoinitiator is a photocurable bioink that can be mixed with hydrogels and cells to safely crosslink bioprinted 3D structures.


  • Photocurable
  • Visible light spectrum of 405nm
  • Can be mixed with hydrogels, bioinks and cells
  • Able to control material stiffness of final structure


Photopolymerization is a common process used for the solidification of materials in a variety of applications including dentistry, optics and tissue engineering. This process, which allows for the fabrication of cell-laden hydrogels from aqueous precursors, offers advantages such as spatial and temporal control, fast curing rates at physiological conditions and minimal heat production.


Photoinitiators are often used in bioprinting as part of the gelation process to solidify bioinks.


LAP (lithium phenyl-2,4,6-trimethylbenzoylphosphinate or LAP) is designed to cross-link photocurable hydrogels and bioinks with cells using Allevi's photocuring module. The key to printing with your Allevi bioprinter. LAP crosslinks within the visible light spectrum of 405 nm. LAP cures within the visible light spectrum which is safer on cells and results in higher cell viability.
