Scalable Fabrication of Height-Variable Microstructures with a Revised Wetting Model

Abstract

Height-Variable Microstructures

In article number 2500234, Nam-Trung Nguyen, Navid Kashaninejad, and Prabuddha De Saram reveal that CO₂ laser-machined PMMA molds enable scalable fabrication of height-variable microstructures in PDMS. The image illustrates the fabrication process and anisotropic wetting behavior on sharkskin-inspired surfaces, enhanced by a revised wetting model.
