Abstract

MERKOCI, A; DEL VALLE, M  and  ALEGRET, S. Bionanostructures and their integration into electrochemical sensing system: A review of DNA applications. Rev. mex. fis. [online]. 2006, vol.52, suppl.2, pp.1-5. ISSN 0035-001X.

Current progress in applying nanoparticles as labels in electrochemical DNA detection systems will be shown. Some aspects of the synthesis of nanoparticles are described, especially the applications of gold nanoparticles or QDs as quantitation tags or electrochemical hosts for DNA detection so as to design what are known as 'chips in solution'.

Keywords : Quantum dots; gold nanoparticles; DNA; electrochemical detection; stripping voltammetry; sensors.
