S. Rana Department of Biotechnology, Deenbandhu Chhotu Ram University of Science and Technology, Sonipat, Haryana, 131039, IN Journal Article 2016 01 27 Abstract Infectious diseases have been on rise in the recent past. Early diagnosis plays a role as important as proper treatment and prophylaxis. The current practices of detection are time consuming which may result in unnecessary delays in treatment. Advances in nanodiagnostic approaches have been in focus lately. The rising interest and better understanding of nanoparticles have led to opening up of new frontiers in the concerned area. Optical properties of nanoparticles are being exploited to design detection systems that can provide fast, one-step and reliable results. Based on conserved DNA sequences unique to the target organism, the results offer accuracy comparable to conventional tests. Further, visual or spectrophotometric analysis omits the need of costly apparatus for result interpretation. The present review aims at putting together the information on nanoparticles based DNA conjugate systems for detection of pathogenic microorganisms.
