An Ink-Enhanced Strategy for High-Fidelity Microstructure and Surface Functionalization of Transparent PDMS Using a UV Nanosecond Laser
Functional micro- and nanostructures are essential for polymer-based devices in biomedicine, sensing, and optics. Yet conventional fabrication methods such as lithography and mold transfer remain expensive, slow, and poorly suited for large-scale production. In this study, we present an ink-enhanced photothermal stra...
