建议到文献求助版块去求助,那里高手特多,只要能找到的文献,一般不超过15分钟就能搞定

Bibliographic Information

Scanometric DNA array detection with nanoparticle probes.     Taton T A; Mirkin C A; Letsinger R L    Department of Chemistry, Center for Nanofabrication and Molecular Self-Assembly, Northwestern University, Evanston, IL 60208, USA      Science (New York, N.Y.)  (2000),  289(5485),  1757-60.  Journal code: 0404511.  ISSN:0036-8075.  United States.  (COMPARATIVE STUDY); Journal; Article; (JOURNAL ARTICLE); (RESEARCH SUPPORT, U.S. GOV'T, NON-P.H.S.); (RESEARCH SUPPORT, U.S. GOV'T, P.H.S.)  written in English.    PubMed ID 10976070 AN 2000440734    MEDLINE

Abstract

A method for analyzing combinatorial DNA arrays using oligonucleotide-modified gold nanoparticle probes and a conventional flatbed scanner is described here.  Labeling oligonucleotide targets with nanoparticle rather than fluorophore probes substantially alters the melting profiles of the targets from an array substrate.  This difference permits the discrimination of an oligonucleotide sequence from targets with single nucleotide mismatches with a selectivity that is over three times that observed for fluorophore-labeled targets.  In addition, when coupled with a signal amplification method based on nanoparticle-promoted reduction of silver(I), the sensitivity of this scanometric array detection system exceeds that of the analogous fluorophore system by two orders of magnitude.
