This paper describes a micro biochip realized on silicon wafers, using standard microfabrication techniques. The biochip is designed to be complex and versatile; it contains a microreactor for the biological material and on the backside of the chip there are heating resistances that would assure the temperature cycles for PCR reactions. The biologic material in the test reactors can be optically monitored because the reactor is covered with transparent glass. The reactor surface was functionalized in order to obtain reactive sites for binding DNA-oligonucleotides for \"in vitro\" DNA identification.","PeriodicalId":40779,"journal":{"name":"Teatro e Storia","volume":"116 1","pages":"235-238 vol. 1"},"PeriodicalIF":0.1,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87700344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
