TWO-COMPONENT BIOINK, 3D BIOMATERIAL COMPRISING THE SAME AND METHOD FOR PREPARING THE SAME

WIPO Patent Application WO/2016/209062

A1

The present invention provides a two-component bioink including a first solution and a second solution separately, wherein (i) the first solution includes a first biopolymer to which a first chemical functional group is introduced, and the second solution includes a second biopolymer to which a second chemical functional group able to chemically bond with the first chemical functional group is introduced; or (ii) the first solution includes a third biopolymer having a first electrostatic functional group, and the second solution includes a fourth biopolymer having a second electrostatic functional group able to physically bond with the first electrostatic functional group, a 3D biomaterial including the same, and a method for preparing the same.
