Facile synthesis of biomimetic honeycomb material with biological functionality.

A microfluidic approach to a honeycomb-structure material based on the synergistic effects of polymer rapid precipitation, double emulsion templating, and internal effervescent salt decomposition is reported. The delicate honeycomb structure exhibits unique characteristics with an external nanopore membrane and internal multiple cavities. The biological functionality of the artificial structure is explored to serve as microcarriers for cell culture and drug release, indicating their attractive properties for potential biomedical applications.
