Volume (to add to vial) ml ul In both formulations, a fixed amount of LAP photoinitiator was added to initiate the radical photopolymerization under UV light. In neutral conditions, DMEM presents light red coloration due to the phenol red molecules used as a pH indicator in the medium. Since the absorbance spectra of phenol red molecules and LAP are partially overlapped, the photoreactivity of the photoinitiator may be. However, LAP concentrations up to 34 mmol/L (1.0 wt %), an atypically high concentration for bioprinting, were not mutagenic in bacteria, even after exposure to light. This study supports that use of LAP photoinitiator and free radicals generated from photo-excited LAP can be cytotoxic to cells undergoing bioprinting.

Toxicity and photosensitizing assessment of gelatin

GelMA is made photosensitive with addition of LAP photoinitiator and is crosslinked with exposure to 405 nm light. Crosslinked GelMA is solid at cell culture temperatures (37 °C) and has a shear elastic modulus proportional to its concentration when fully crosslinked. Both LAP concentration and 405 nm light intensity are positively correlated with crosslinking rate, but do not affect final elastic modulu For example, the type I photoinitiator lithium acylphosphinate (LAP) has been widely used for the formation of thiol-ene hydrogels in the presence of live cells owing to the favorable water solubility, cytocompatibility, and rapid and efficient initiation that LAP affords with low doses of long wavelength UV light (365 nm). 9 Further, by increasing the concentration of LAP, broad spectrum visible light (400-700 nm) has been demonstrated for the formation of thiol-ene hydrogels. Here, the photoinitiator LAP was selected since it is a water-soluble, visible light photoinitiator that has limited cytotoxicity and has been previously employed towards the formation of HA-based. Common type II photoinitiator systems include Benzophenone, 2-Isopropylthioxanthone, 4-Methylbenzophenone, Ethyl 4-dimethylaminobenzoate, 4-Chlorobenzophenone, etc. Cationic Photoinitiators . The mechanism of a photoinduced cationic initiation is shown below for a triarylsulfonium salt.

In fact, radical photoinitiators are divided into two types: photo-cleavable (type I) and biomolecular (type II) photoinitiators based on their mechanism in the production of free radicals. Type I photoinitiators such as benzoin derivatives and acetophenone derivatives have been commonly used . Upon exposure to light, type I photoinitiators take up incident photons and decay into two primary radicals that initiate the photocrosslinking reaction. Type II photoinitiators, such as. Mixtures of PEG-DA polymer, Lns, and LAP photoinitiator were prepared largely as described previously 14. In general, premixed formulas (250 μL in total) were generated by varying the ratios of. This disulfide cross-linked hydrogel was swollen in a solution of a lithium acylphosphinate (LAP) photoinitiator, recently demonstrated to possess a higher efficiency and quantum yield than alternative water-soluble cleavage-type radical photoinitiators

More recently, a Type-I visible light photoinitiator (lithium phenyl-2,4,6-trimethylbenzoylphosphinates, LAP, λ max ∼375 nm) has proven to be much more efficient and less cytotoxic than I2959, thus making it a better photoinitiator for in situ cell encapsulation studies [31]
