Shape dependent sensing potential of gold nanoparticles in etching based multicolorimetric plasmonic-ELISA
Sangeeta Yadav, Jitendra Satija
Abstract
(∼6.54 aM) without the aid of any sophisticated instruments. In the future, the developed competitive p-ELISA strategy can be easily employed to develop cost-effective, portable, and point-of-care assays for the detection of various disease biomarkers with ultra-high sensitivity.
