JenKem Technology has developed a novel photo-initiator (M-QTX) with good water-solubility, biocompatibility, and low cytotoxicity, for 3D bioprinting of PEG-based hydrogels.
Hydrogels 3D printed through SLA (stereolithography) at 380-420 nm using M-QTX and multiarm PEG and PEG-PCL acrylate and methacrylate derivatives are transparent, with well-defined shape. These low toxicity, biocompatible hydrogels are suitable for tissue engineering, organ engineering, and 3D cell culture.
Please contact us for details on the product and for quotation purposes.
