US 2026/0297344 A1 · BIOINK COMPOSITIONS FOR VISIBLE LIGHT CURING, METHOD OF MANUFACTURING THE SAME, AND METHOD OF PRINTING THE SAME

Abstract

The present invention relates to bioink compositions for visible light curing, method of manufacturing the same, and method of printing the same. More particularly, the bioink composition comprises an extracellular matrix (dECM) obtained by treating decellularized tissue isolated from a living body and ruthenium/sodium persulfate (Ru/SPS) as a photoinitiator, which is photocrosslinked by visible light irradiation. This composition exhibits excellent mechanical properties due to physical crosslinking through intermolecular interactions, along with superior cell compatibility and high shape retention.

Dependent claims

A method for manufacturing a bioink composition, the method comprising the steps of:

preparing an extracellular matrix (ECM) by treating tissue separated from a living body with a decellularization process;
manufacturing decellularized Extracellular matrix Ruthenium Sodium persulfate (dERS) by mixing Ruthenium/Sodium PerSulfate (Ru/SPS) as a photoinitiator with the prepared decellularized extracellular matrix (dECM);
and
irradiating visible light onto the manufactured decellularized Extracellular matrix Ruthenium Sodium persulfate (dERS) to photocrosslink the same.
