Hybrid gold nanocube@silica@graphene-quantum-dot superstructures: synthesis and specific cell surface protein imaging applications†
Abstract
Hybrid AuNCs@SiO2@GQDs nanocomposites were synthesized via a multistep procedure; GQDs located near AuNCs showed enhanced fluorescent intensities and improved photostabilities. AuNCs@SiO2@GQDs nanocomposites allowed specific visualization of EGFR on cancer cells.
