40nm Carboxylated (carboxyl-PEG5000-SH) Silver Nanoparticles Size:1ML Cytodiagnostics PEGylated Gold NanoUrchins with

Cytodiagnostics PEGylated Gold NanoUrchins with carboxyl functional groups are made using a unique proprietary protocol resulting in particles with superior size distribution and shape compared to the leading competitor and are ideal for development of covalent gold nanourchin conjugates

Cytodiagnostics PEGylated gold nanorods are extensively purified after synthesis which reduces contaminants from manufacturing that might interfere with sensitive downstream applications
