Abstract

Photolithography Traditional photoresists used in photolithography are typically toxic, nonaqueous substances that require harsh processing conditions, which limits the development of biofunctional and biocompatible micropatterns. In article number 2411900, Xiaorui Zheng, Chengchen Guo, and colleagues introduce a protein-based aqueous photoresist derived from chemically modified silk fibroin. This photoresist employs an entirely water-based process to achieve high-resolution multiplexed micropatterning with designed functionalities, demonstrating significant potential in biomedical applications.
