    Abstract

    The fabrication of three-dimensional (3D) metal microstructures in a synthetic polymer-based hydrogel is demonstrated by femtosecond laser-induced photoreduction. The linear-shaped silver structure of approximately 2 micrometers in diameter is fabricated inside a biocompatible poly(ethylene glycol) diacrylate (PEGDA) hydrogel. The silver structure is observed and confirmed by scanning electron microscopy (SEM) and elemental analysis using energy-dispersive X-ray spectroscopy (EDX). Shrinking and swelling of the fabricated structure is also demonstrated experimentally, which shows the potential of the present method for realizing 3D flexible electronic and optical devices, as well as for fabricating highly integrated devices at submicron scales.
