Why the Photoinitiator LAP Became the De Facto Standard for Hydrogels, GelMA, and Bioprinting: Balancing Efficiency, Safety, and Water Solubility
In fields such as hydrogels, GelMA, and 3D bioprinting—where materials must cure while simultaneously protecting living cells—choosing a photoinitiator is never a single-criterion decision. It must be efficient, safe, water-soluble, formulation-friendly, and proven at scale, and few molecules satisfy all of these conditions at once. LAP (ChemWhat Code 1208803) is one of the rare answers
