Volume 3, Issue 2 , Spring 2018, , Pages 102-108

http://dx.doi.org/10.22034/nmrj.2018.02.007

Abstract
  In this paper, a fast and sensitive localized surface plasmon resonance (LSPR) based biosensor was developed and the optimization of gold – antibody conjugates through investigation of different parameters were performed. Gold nanoparticles (AuNPs) with a size of ~20 nm were synthesized via chemical ...  Read More
