Enhanced adhesion in two-photon polymerization direct laser writing

Enhanced adhesion in two-photon polymerization direct laser writing

We have quantified the adhesion forces between two-photon polymerization direct laser writing (TPP-DLW) microstructures and glass surfaces with and without an adhesion promoter. Glass surfaces treated with an acryloxy-silane agent produce adhesion forces that are almost three times larger than the f...
