Abstract

Recently, we reported our methodology for isolating plasma membrane and lysosome from eukaryotic cell using superparamagnetic nanoparticles (SPMNPs). Here in this article, we report a step-by-step protocol for synthesis of hybrid gold nanoparticle (AuNP), surface functionalization of AuNPs on superparamagnetic nanoparticles (SPMNPs), and potential use of hybrid AuNP-SPMNP for efficient coupling of biomolecules.

Keywords: AuNPs; Bio-conjugation; Phospholipids; SPMNPs.
