Three-dimensionally shaped microstructures has featured advanced functionalities in biotechnology, photonics, and self-assembly. We developed a novel lithographic approach to fabricate psuedo-3D microstructures using the reaction-diffusion process. In this work, the Reaction-Diffusion-Mediated Photolithography (RDP) process is further studied to investigate effect of various parameters on growth behavior of microstructure. We expand the use of microstructure to a wide range of structural dimensions and optimize the conditions along with the separation between reaction sites. In addition, we investigate how a lens effect dynamically guides the growth behavior of microstructures in combination with the reaction-diffusion process. High reproducibility and simple experimental setup of the RDP process will open new opportunities to fabricate microparticles or micropattern with unique pseudo-3D structures. |
