Here we present the replication of the Pieris rapae butterfly optical structure. This butterfly has white wings with black spots. The white coloration is produced by light scattering on pterin beads ranging from 100 to 500 nm whereas black spots correspond to areas without pterin beads, thus revealing a highly pigmented layer underneath. In order to mimic the butterfly wing structure, we deposited SU-8 beads produced by electrospraying on a black absorbing layer made of black SU-8. We thereby replicated the optical effect observed on Pieris rapae. Additional experiments showed that the white coloration replication is a structural color. Finally, we further demonstrate that these optical engineered surfaces can be used for sucrose sensing in the range of 1 g\/L  to 250 g\/L.<\/jats:p>","DOI":"10.3390\/mi5020216","type":"journal-article","created":{"date-parts":[[2014,4,23]],"date-time":"2014-04-23T12:29:40Z","timestamp":1398256180000},"page":"216-227","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Biomimetic Pieris rapae\u2019s Nanostructure and Its Use as a Simple Sucrose Sensor"],"prefix":"10.3390","volume":"5","author":[{"given":"David","family":"Bonzon","sequence":"first","affiliation":[{"name":"Laboratoire de Microsyst\u00e8mes LMIS4, Ecole Polytechnique F\u00e9d\u00e9rale de Lausanne, Station 17,  CH-1015 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8023-1161","authenticated-orcid":false,"given":"Rodrigo","family":"Martinez-Duarte","sequence":"additional","affiliation":[{"name":"Mechanical Engineering Department, Clemson University, 250 Fluor Daniel, Clemson, SC 29634, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Renaud","sequence":"additional","affiliation":[{"name":"Laboratoire de Microsyst\u00e8mes LMIS4, Ecole Polytechnique F\u00e9d\u00e9rale de Lausanne, Station 17,  CH-1015 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"Madou","sequence":"additional","affiliation":[{"name":"Mechanical and Aerospace Engineering Department, University of California Irvine,  4200 Engineering Gateway, Irvine, CA 92617, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2014,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s004250050096","article-title":"Purity of the sacred lotus, or escape from contamination in biological surfaces","volume":"202","author":"Barthlott","year":"1997","journal-title":"Planta"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"4049","DOI":"10.1002\/adma.200800651","article-title":"Biomimetic artificial surfaces quantitatively reproduce the water repellency of a lotus leaf","volume":"20","author":"Zorba","year":"2008","journal-title":"Adv.
