Micropattern of core-shell Ag@MCS/PEGDA nanoparticles fabricated by femtosecond laser maskless optical projection lithography

Abstract

Highlights Ag/CS nanomaterials can be prepared via Fs-MOPL in one-step in a short time. Hydrogel-based core-shell micropatterns are achieved by Fs-MOPL technique for the first time. Amino and hydroxyl groups greatly affect the number of Ag@MP nanocomposites. The formation mechanism is explained by LSPR and the nucleation and growth theory.
