Micromasonry is a fabrication technique to self-assemble micrometric and sub-micrometric three-dimensional units into larger structures.[1] The technique is based on the self-assembly construction and hierarchical design of biological materials.

Self-assembly of 3D biological units by Micromasonry

It was developed by Spanish materials scientist Javier G. Fernandez of the Massachusetts Institute of Technology to produce artificial organs by self-assembling groups of biological cells in biocompatible polymers. This method allows the self-assembly of encapsulated cells in 3D geometries, enabling the fabrication of biological tissue following an approach similar to building a brick structure. Because this bottom-up method of fabrication, the resulting constructions are some times referred as "bio-Legos".[2]

Micromasonry is considered an important breakthrough in fabrication for modern tissue engineering,[3] for its simplicity, efficiency, and for being the major example in the merge of microelectronic engineering techniques and biological functionality.[4]

Since its development, micromasonry has been extensively employed for the construction of cell-laden organ replacements and 3D microelectronics.[5]

Terminology[edit]

Micromasonry is often referred as "bio-legos" or "biological legos" because its extensive use for the construction of biological tissue.
