Abstract

Here we report on the design, synthesis and application of small, highly bright, star-shaped SERS encoded single nanoparticles with the ability of providing an optical signal upon excitation with near infrared light. These particles are colloidally stable, fully biocompatible and can be internalized into living cells for intracellular imaging.
