In a pioneering fusion of mussel-inspired materials (MIMs) and state-of-the-art multiphoton direct laser writing microfabrication, our latest research addresses the critical demand for multifunctional materials and high-precision surface modification techniques essential for advancing microdevices and sensing elements. This study showcases the versatility of MIMs, unveiling 2D and 3D microstructures with sub-micron to micron resolution and extensive post-functionalization capabilities.
Employing polydopamine, mussel-inspired linear, and dendritic polyglycerols, we enable direct microstructure fabrication on the substrate of choice, providing unprecedented control over patterned topography and morphology. Demonstrating the multi-functional potential of MIMs, we successfully immobilize and detect single-stranded DNA and seamlessly integrate silver nanoparticles into MIM microstructures without the need for reducing agents. The proposed methodology paves the way for the integration of MIMs into advanced applications where precise surface functionalization is of paramount importance, opening up new possibilities in materials science and microfabrication.
