In particular, biomineralization approaches exploit efficient pathways of inorganic material synthesis. There is still a large gap between the complexity of natural systems and the practical utilization of bioinspired formation mechanisms. Here we describe a simple self-assembly route leading to a CaCO3 microlens array, somewhat reminiscent of the brittlestars’ microlenses, with uniform size and focal length, by using a minimum number of components and equipment at ambient conditions. The formation mechanism of the amorphous CaCO3 microlens arrays was elucidated by confocal Raman spectroscopic imaging to be a two-step growth process mediated by the organic surfactant. CaCO3 microlens arrays are easy to fabricate, biocompatible and functional in amorphous or more stable crystalline forms. This shows that advanced optical materials can be generated by a simple mineral precipitation.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: Nature Communications ; 3 (2012). - 725</dcterms:bibliographicCitation> <dc:creator>Cölfen, Helmut</dc:creator> <dc:creator>Kommareddy, Krishna</dc:creator> <dc:contributor>Bennet, Mathieu</dc:contributor> <bibo:uri rdf:resource=""/> <dc:contributor>Manjubala, Inderchand</dc:contributor> <dc:creator>Park, Seung</dc:creator> <dc:contributor>Masic, Admir</dc:contributor> <dc:contributor>Fratzl, Peter</dc:contributor> <dc:creator>Fratzl, Peter</dc:creator> <dc:contributor>Park, Seung</dc:contributor> <dc:contributor>Kommareddy, Krishna</dc:contributor> <dc:contributor>Cölfen, Helmut</dc:contributor> <dc:date rdf:datatype="">2012-03-29T09:46:16Z</dc:date> <dcterms:issued>2012</dcterms:issued> <dc:contributor>Lee, Kyubock</dc:contributor> <dcterms:available rdf:datatype="">2012-09-06T22:25:05Z</dcterms:available> <dcterms:rights rdf:resource=""/> <dc:creator>Bennet, Mathieu</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:contributor>Lee, Seung-Woo</dc:contributor> </rdf:Description> </rdf:RDF>
