Biomimetic Replication of Microscopic Metal-Organic Framework Patterns Using Printed Protein Patterns

Adv Mater. 2015 Dec 2;27(45):7293-8. doi: 10.1002/adma.201503167. Epub 2015 Oct 19.

Abstract

It is demonstrated that metal-organic frameworks (MOFs) can be replicated in a biomimetic fashion from protein patterns. Bendable, fluorescent MOF patterns are formed with micrometer resolution under ambient conditions. Furthermore, this technique is used to grow MOF patterns from fingerprint residue in 30 s with high fidelity. This technique is not only relevant for crime-scene investigation, but also for biomedical applications.

Keywords: biomineralization; metal-organic frameworks; nanolithography; printing; protein patterns.
