We have studied fabrication of these nano materials such as one dimensional nanowires and nanoholes by \u201cself-organization\u201d processes. We developed these technologies for fabrication of next generation nonvolatile memories, 3-dimensional interconnections, biochemical sensors, bio-mimetics, and solar batteries, etc. Our original technologies are; (1) formation of nanohole array on Si using anodic oxidation of sputtered Al films, (2) growth of single crystalline Si nanowires perpendicular to Si (001) substrate, (3) CuSn nanotrees formed by electroplating, etc. These topics have been developed by collaboration between foreign research institutes and Japanese companies.

It has been reported in the 1990s that the ordered array of nanoholes between a few tens to hundreds nm are formed perpendicular to substrate in oxalic acid, surfuric acid, and phousphoric acid. We deposited various materials such as metals and semiconductors by electroplating as well as electroless plating in the AAO nanoholes on Si o SiO2 substrate.

interaction such as PPI (protein-protein interaction) is very important for living organisms to maintain the life activity. In particular, PPIs are studied for drug discovery and basic medicine. For monitoring PPIs, many techniques are suggested based on photo fluorescence. However, this technique needs to label fluorescence materials. To monitor PPIs on the real time, some techniques such as SPR (surface plasmon resonance) and QCM (quartz crystal microbalance) are widely spread. These techniques have sensing devices, in fact, biosensors. Our group develops devices to monitor PPIs and complicated deformation of biomolecules using LSPR (Localized Surface Plasmon Resonance) and QCM. We develop these devices to improve the sensitivity by using nano structures which have large surface area.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"280\" src=\"http:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research07.jpeg\" alt=\"\" class=\"wp-image-169\" srcset=\"https:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research07.jpeg 750w, https:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research07-300x112.jpeg 300w, https:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research07-360x134.jpeg 360w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><figcaption class=\"wp-element-caption\"> \u56f3\uff1a\u5de6\uff1d\u30ac\u30e9\u30b9\u57fa\u677f\u4e0a\u306b\u4f5c\u88fd\u3057\u305f\u91d1\u30ca\u30ce\u30d4\u30e9\u30fc\u30a2\u30ec\u30fc\u306e\u96fb\u5b50\u9855\u5fae\u93e1\u5199\u771f\u3000\u53f3\uff1d\u30b7\u30ea\u30b3\u30f3\u57fa\u677f\u4e0a\u306b\u4f5c\u88fd\u3057\u305fZnO\u30ca\u30ce\u30d4\u30e9\u30fc\u30a2\u30ec\u30fc\u306e\u96fb\u5b50\u9855\u5fae\u93e1\u5199\u771f <\/figcaption><\/figure>\n<\/div>\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"06\">\u30d0\u30a4\u30aa\u30df\u30e1\u30c6\u30a3\u30af\u30b9\u5206\u91ce\u3000Biomimicry<br>\u4f0a\u85e4\u6559\u6388 Prof. Ito<\/h2>\n\n\n\n<p>\u3000\u751f\u7269\u304c\u305d\u306e\u9032\u5316\u306e\u904e\u7a0b\u3067\u5f97\u3066\u304d\u305f\u305d\u306e\u751f\u7269\u7279\u6709\u306e\u7279\u5fb4\u7684\u306a\u6a5f\u80fd\u304c\u30af\u30ed\u30fc\u30ba\u30a2\u30c3\u30d7\u3055\u308c\u3066\u3044\u307e\u3059\u3002\u30d0\u30a4\u30aa\u30df\u30e1\u30c6\u30a3\u30af\u30b9\u306f\u3001\u305d\u306e\u3088\u3046\u306a\u751f\u7269\u304c\u6301\u3064\u7279\u5fb4\u7684\u306a\u6a5f\u80fd\u3092\u771f\u4f3c\u308b\u3053\u3068\u3067\u4eba\u985e\u306b\u5f79\u7acb\u3064\u6280\u8853\u3092\u5275\u51fa\u3059\u308b\u7814\u7a76\u5206\u91ce\u3067\u3042\u308a\u3001\u30d0\u30a4\u30aa\u30df\u30df\u30af\u30ea\u30fc\u306a\u3069\u3068\u3082\u547c\u3070\u308c\u3066\u3044\u307e\u3059\u3002\u79c1\u305f\u3061\u306f\u3001\u7279\u306b\u751f\u7269\u306e\u6301\u3064\u30ca\u30ce\u30fb\u30de\u30a4\u30af\u30ed\u69cb\u9020\u3068\u305d\u306e\u6a5f\u80fd\u306b\u7740\u76ee\u3057\u3066\u3044\u307e\u3059\u3002\u3053\u308c\u3089\u306e\u69cb\u9020\u306f\u3001\u81ea\u5df1\u7d44\u7e54\u5316\u3055\u308c\u3066\u304a\u308a\u3001\u4f4e\u74b0\u5883\u8ca0\u8377\u3067\u4f5c\u3089\u308c\u308b\u305f\u3081\u5de5\u696d\u7684\u306b\u898b\u3066\u3082\u6709\u7528\u3067\u3059\u3002<br>\u3000\u73fe\u5728\u306f\u3001\u30bb\u30df\u306e\u7fbd\u306e\u8868\u9762\u306b\u3042\u308b\u30ca\u30ce\u69cb\u9020\u306b\u7740\u76ee\u3057\u3001\u305d\u306e\u30ca\u30ce\u69cb\u9020\u304c\u6301\u3064\u6297\u83cc\u6027\u306b\u3064\u3044\u3066\u7814\u7a76\u3092\u884c\u3063\u3066\u3044\u307e\u3059\u3002\u30dc\u30c8\u30e0\u30a2\u30c3\u30d7\u6280\u8853\u3092\u4f7f\u3063\u3066\u30b7\u30ea\u30b3\u30f3\u57fa\u677f\u4e0a\u306b\u7121\u6570\u306e\u30ca\u30ce\u69cb\u9020\u3092\u4f5c\u88fd\u3059\u308b\u3053\u3068\u3067\u6a21\u5023\u306b\u6210\u529f\u3057\u307e\u3057\u305f\u3002\u307e\u305f\u3001\u3053\u306e\u30ca\u30ce\u69cb\u9020\u3092\u8868\u9762\u306b\u6301\u3064\u30b7\u30ea\u30b3\u30f3\u57fa\u677f\u306f\u3001\u5927\u8178\u83cc\u306b\u5bfe\u3057\u3066\u6297\u83cc\u6027\u3092\u793a\u3059\u3053\u3068\u3092\u660e\u3089\u304b\u306b\u3057\u3066\u304d\u307e\u3057\u305f\u3002\u4eca\u5f8c\u306f\u3001\u3053\u308c\u3089\u306e\u5927\u91cf\u751f\u7523\u3078\u5411\u3051\u305f\u53d6\u308a\u7d44\u307f\u306b\u3088\u308a\u98df\u54c1\u5206\u91ce\u306a\u3069\u3078\u5c55\u958b\u3057\u3066\u3044\u304d\u307e\u3059\u3002<\/p>\n\n\n\n<p>\u3000Biomimetics is one of the hot topics in the world. Recently, observation techniques such as SEM, TEM and AFM are widely spread, and we can use them easily to discuss the nano and micro-structures of living organisms. They acquire functional nano and micro structures along the course of evolution. In addition, nano and micro fabrication techniques based on top down process and bottom up process grow up. Then, we can fabricate nano and micro-structures to mimic that of living organism.<br>We pay attention for cicada\u2019s wing because it shows the antireflection, super hydrophobic, low friction and antibacterial property. In particular, antibacterial property is very unique and expressed due to physicochemical property of its structure. Our group fabricates Si nanopillars by metal assisted chemical etching and shows their antibacterial property. Now, we try to work out the mechanism of antibacterial property.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"430\" src=\"http:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research08.jpeg\" alt=\"\" class=\"wp-image-170\" srcset=\"https:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research08.jpeg 750w, https:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research08-300x172.jpeg 300w, https:\/\/wps.itc.kansai-u.ac.jp\/nano\/wp-content\/uploads\/sites\/246\/2022\/02\/research08-360x206.jpeg 360w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><figcaption class=\"wp-element-caption\"> \u56f3\uff1a\u5de6\uff1d\u30af\u30de\u30bc\u30df\u306e\u7fbd\u3068\u96fb\u5b50\u9855\u5fae\u93e1\u306b\u3088\u308b\u89b3\u5bdf\u4f8b\u3000\u53f3\uff1d\u30af\u30de\u30bc\u30df\u306e\u7fbd\u8868\u9762\u306b\u3042\u308b\u30ca\u30ce\u69cb\u9020\u3092\u6a21\u3057\u3066\u4f5c\u88fd\u3057\u305f\u30b7\u30ea\u30b3\u30f3\u57fa\u677f\u306e\u96fb\u5b50\u9855\u5fae\u93e1\u5199\u771f <\/figcaption><\/figure>\n<\/div>\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"01\">\u9ad8\u30a8\u30cd\u30eb\u30ae\u30fc\u91cf\u5b50\u5909\u63db\u5206\u91ce\u3000<br>\u5e02\u5834\u52a9\u6559 Asst.
