Low Toxicity Photoinitiator for 3D Printing: M-QTX


Made-to-order. Please contact us for lead time


JenKem Technology has recently developed M-PEG-QTX, a novel photo-initiator with good water-solubility, biocompatibility, and low cytotoxicity, for 3D bioprinting of PEG-based hydrogels.

  • Novel biocompatible photo-initiator with low cytotoxicity and good water-solubility
  • Multiarm PEG and PEG-PCL acrylate and methacrylate derivatives for 3D printing hydrogels via stereolithography
  • Wavelength range: 380-420nm
  • Low toxicity biocompatible hydrogels are suitable for tissue and organ engineering, and 3D cell culture
  • 3D printed hydrogels are transparent with well-defined shape

3D printed PEG hydrogel. Precursor aqueous solution of JenKem® 8ARM(TP)-ACLT-10K, and photo-initiator M-PEG-QTX.

Hydrogels 3D printed through SLA (stereolithography) 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.

Photoinitiators with different MW may be made-to-order. Please inquire at tech@jenkemusa.com about pricing and availability of custom PEGs.
