Gold Nanoparticle Based Microbial Detection and Identification

I had an opportunity to read a very interesting and exciting paper on the use of gold nanoparticles for the detection and identification of microorganisms. Below you will find the reference and a brief abstract, and I will be providing a more detailed review of the paper in our next Newsletter, due out later this week.

Gold nanoparticle based microbial detection and identification. Muhammad Ali Syed, S Habib Ali Bokhari. J Biomed Nanotechnol. 2011 Apr;7(2):229-37.


Microorganisms belong to one of the biggest threats to humanity. Rapid detection and identification of microbes in environmental, food and clinical samples is required for safety purposes as well as diagnosis of infectious diseases. Conventional techniques for microbial detection, though reliable and gold standard, are time consuming, expensive and unsuitable for field situations. Advent of novel techniques involving Nanotechnology has been promising for the development of rapid and low cost strategies for rapid detection and identification of microbes with higher sensitivity. Gold nanoparticles find a significant place in medicine, material sciences as well as diagnostics for their unique optical and physiochemical properties. This review focuses at recent advancements in the development of gold nanoparticle based assays for microbial detection and identification.
