What is the advantage of flow printing?

Flow printing enables printing ligands in a 4x12 matrix in a single run. Up to three printings can be repeated on our SPRi-Biochip. Each spot has its individual network of inlet and outlet tubes, reducing the risks for cross-contamination. The ligand is immobilized using a back-and-forth movement for increased spot homogeneity. Flow printing can be used with both 2D and 3D (Dextran-based) surface chemistries. More information on the SPRi-CFM printer can be found here.
