Conversely, the antifouling effect of cicada wings arises from their microstructured or nanostructured surface. These structures trap and rupture adherent microorganisms, which prevent biofilm formation and enable effective antifouling. This study used two typical gram-positive pathogenic strains\u2014the rod-shaped\n                      <jats:italic toggle=\"yes\">Bacillus cereus<\/jats:italic>\n                      and the coccus-shaped\n                      <jats:italic toggle=\"yes\">Staphylococcus aureus<\/jats:italic>\n                      \u2014as model microorganisms.

Additionally, the interfacial morphological evolution during bacteria\u2013structure interaction was visualized via scanning electron microscopy\/transmission electron microscopy, aiming to elucidate how physical disruption compromises bacterial cellular integrity. The results show that the nanopillar surface exhibits potent bactericidal activity against both gram-positive species, with\n                      <jats:italic toggle=\"yes\">B. cereus<\/jats:italic>\n                      consistently showing higher killing efficiency. This bactericidal effect is not mediated by chemical composition but rather follows a purely physical \u201cadhere\u2013deform\u2013rupture\u201d mechanism. This mechanism has revolutionized the design paradigm of antibiofilm materials, enabling a shift from passive exclusion to an active \u201ccapture\u2013and\u2013kill\u201d dual-function strategy.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>The colonization and spread of bacteria pose significant biosafety threats to several key industries, including healthcare, food, pharmaceuticals, and biotechnology. To mitigate these risks, the current industry commonly employs intervention measures such as the addition of antibiotics, treatment with chemical disinfectants, and application of antibacterial chemical coatings. However, these chemical sterilization methods may potentially have adverse effects on human health. In contrast, the cicada wing surface, with its natural micro- and nanostructures, exhibits physical antibacterial properties that achieve efficient sterilization while avoiding the health risks associated with chemical agents, thus offering a new approach to safe antibacterial strategies.<\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.02037-25","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T13:57:18Z","timestamp":1768226238000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Mechano-bactericidal activity of cicada wing nanostructures against gram-positive bacteria"],"prefix":"10.1128","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-4442-3328","authenticated-orcid":true,"given":"Jianwei","family":"Qu","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01n7x9n08","id-type":"ROR","asserted-by":"publisher"}],"name":"Shenyang Agricultural University","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiya","family":"Gu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01n7x9n08","id-type":"ROR","asserted-by":"publisher"}],"name":"Shenyang Agricultural University","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Chen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01n7x9n08","id-type":"ROR","asserted-by":"publisher"}],"name":"Shenyang Agricultural University","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fangming","family":"Cui","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01n7x9n08","id-type":"ROR","asserted-by":"publisher"}],"name":"Shenyang Agricultural University","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huan","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01n7x9n08","id-type":"ROR","asserted-by":"publisher"}],"name":"Shenyang Agricultural University","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1491-5204","authenticated-orcid":false,"given":"Liyan","family":"Wu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01n7x9n08","id-type":"ROR","asserted-by":"publisher"}],"name":"Shenyang Agricultural University","place":["Shenyang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/antibiotics12111590"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(21)02724-0"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.glmedi.2024.100081"},{"key":"e_1_3_3_5_2","unstructured":"World Health Organization. 2019.
