The moth-eye film has artificially formed nano-pillars, consisting of hydrophilic resin with urethane acrylate and polyethylene glycol (PEG) derivatives, all over its surface that replicates a moth\u0027s eye. Experiments were performed to compare the moth-eye film with a flat-surfaced film produced from the same materials. The JIS Z2801 film-covering method revealed that the two films produced a decrease in Staphylococcus aureus and Esherichia coli titers of over 5 and 3 logs, respectively. There was no marked difference in the antibacterial effects of the two surfaces. However, the antibacterial effects were reduced by immersion of the films in water. These results indicated that a soluble component(s) of the resin possessed the antibacterial activity, and this component was identified as PEG derivatives by time-of-flight secondary ion mass spectrometry (TOF-SIMS) and Fourier transform infrared spectroscopy (FT-IR). When a small volume of bacterial suspension was dropped on the films as an airborne droplet model, both films showed antibacterial effects, but that of the moth-eye film was more potent. It was considered that the moth-eye structure allowed the bacteria-loaded droplet to spread and allow greater contact between the bacteria and the film surface, resulting in strong adherence of the bacteria to the film and synergistically enhanced bactericidal activity with chemical components. The antibacterial effect of the moth-eye film has been thus confirmed under a bacterial droplet model, and it appears attractive due to its antibacterial ability, which is considered to result not only from its chemical make-up but also from physical adherence."}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "metadata only access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_14cb"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Antibacterial Effect of Artificial Surface of Nanoimprinted Moth-eye Film", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Antibacterial Effect of Artificial Surface of Nanoimprinted Moth-eye Film", "subitem_title_language": "en"}]}, "item_type_id": "3", "owner": "40", "path": ["294"], "permalink_uri": "https://gifu-pu.repo.nii.ac.jp/records/13269", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-06-21"}, "publish_date": "2018-06-21", "publish_status": "0", "recid": "13269", "relation": {}, "relation_version_is_last": true, "title": ["Antibacterial Effect of Artificial Surface of Nanoimprinted Moth-eye Film"], "weko_shared_id": -1}
