The adhesion of artificial hydrophilic (silica) and hydrophobic (C\n            <jats:sub>18<\/jats:sub>\n            ) spherical particles and natural pollen grains were measured by atomic force microscopy and demonstrated extremely low values comparable to those recorded on superhydrophobic insects. The lizard scales which exhibited a three-tier hierarchical architecture demonstrated higher adhesion than the trough regions between scales. The two-tier roughness of the troughs comprising folding of the skin (wrinkling) limits the number of contacting hairs with particles of the dimensions used in our study. The gecko skin architecture on both the dorsal and trough regions demonstrates an optimized topography for minimizing solid\u2013solid and solid\u2013liquid particle contact area, as well as facilitating a variety of particulate removal mechanisms including water-assisted processes. These contrasting skin topographies may also be optimized for other functions such as increased structural integrity, levels of wear protection and flexibility of skin for movement and growth. While single hair adhesion is low, contributions of many thousands of individual hairs (especially on the abdominal scale surface and if deformation occurs) may potentially aid in providing additional adhesional capabilities (sticking ability) for some gecko species when interacting with environmental substrates such as rocks, foliage and even man-made structuring.\n          <\/jats:p>","DOI":"10.1098\/rsif.2015.0318","type":"journal-article","created":{"date-parts":[[2015,6,10]],"date-time":"2015-06-10T18:09:43Z","timestamp":1433959783000},"page":"20150318","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":23,"title":["Contaminant adhesion (aerial\/ground biofouling) on the skin of a gecko"],"prefix":"10.1098","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9843-9211","authenticated-orcid":false,"given":"Gregory S.","family":"Watson","sequence":"first","affiliation":[{"name":"School of Science and Engineering, Faculty of Science, Health, Education and Engineering, University of the Sunshine Coast, Maroochydore DC, Queensland 4558, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6309-1400","authenticated-orcid":false,"given":"Bronwen W.","family":"Cribb","sequence":"additional","affiliation":[{"name":"Centre for Microscopy and Microanalysis and School of Biological Sciences, The University of Queensland, St Lucia, Queensland 4072, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1009-670X","authenticated-orcid":false,"given":"Lin","family":"Schwarzkopf","sequence":"additional","affiliation":[{"name":"School of Marine and Tropical Biology, James Cook University, Townsville, Queensland 4811, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5027-9025","authenticated-orcid":false,"given":"Jolanta A.","family":"Watson","sequence":"additional","affiliation":[{"name":"School of Science and Engineering, Faculty of Science, Health, Education and Engineering, University of the Sunshine Coast, Maroochydore DC, Queensland 4558, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2015,7,6]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmatsci.2012.03.001"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1098\/rsta.2009.0022"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcis.2013.05.028"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1039\/C4TA02071E"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1210770110"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004250050096"},{"key":"e_1_3_5_8_2","first-page":"1170","article-title":"Self-propulsion of dew drops on Lotus leaves: a potential mechanism for self-cleaning","volume":"208","author":"Watson GS","year":"2014","journal-title":"Biofouling"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.1080\/08927014.2011.637187"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsb.2010.03.008"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.051128"},{"key":"e_1_3_5_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bpj.2010.12.3736"},{"key":"e_1_3_5_13_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0408304102"},{"key":"e_1_3_5_14_2","doi-asserted-by":"publisher","DOI":"10.1098\/rsif.2012.0108"},{"key":"e_1_3_5_15_2","doi-asserted-by":"publisher","DOI":"10.1093\/icb\/42.6.1154"},{"key":"e_1_3_5_16_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1219317110"},{"key":"e_1_3_5_17_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0506328102"},{"key":"e_1_3_5_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.actbio.2007.01.007"},{"key":"e_1_3_5_19_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.192252799"},{"key":"e_1_3_5_20_2","doi-asserted-by":"publisher","DOI":"10.1529\/biophysj.105.065268"},{"key":"e_1_3_5_21_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2013.2160"},{"key":"e_1_3_5_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/B0-72-169327-X\/50020-1"},{"key":"e_1_3_5_23_2","doi-asserted-by":"publisher","DOI":"10.1080\/11263500012331350495"},{"key":"e_1_3_5_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-2113(03)80001-9"},{"key":"e_1_3_5_25_2","first-page":"300","article-title":"Aerobiology as a tool to help in episodes of occupational allergy in work places","volume":"14","author":"Cari\u00f1anos P","year":"2004","journal-title":"J.
