摘要
To fabricate the more complex structures, developing simplified methods will create greater utility for researchers. Herein, we present a method to build three-dimensional structures through the optical method combined with photoactivation chemistry and Al2O3 nanopore membrane. This phase transition reaction in this material was initiated by the UV-light energy from the fluorescent microscope. This method merges an optical approach along with phase shifting chemical restructuring through the transition of the chemical from an aqueous to a solid phase. We also fabricated the square three-dimensional microstructure based on this method. This method has potential applications in a variety of fields, which include building three-dimensional complex structures such as microfluidics, lab-on-chip and small-scale scaffolds for tissue engineering.
