High-Yield Tc Labeling of Gold Nanoparticles Carrying Atropine and Adrenaline.

This work focuses on the synthesis, purification, and analytical characterization of novel multifunctional Au NPs radiolabeled with Tc. These mixed-ligand shell Au NPs represent pharmacologically relevant samples for potential application in theragnostics. A ligand using a plain linker with a rather long chain consisting of 10 CH groups and a thiol moiety along with the PADA chelator has been used for both the attachment to the Au NP surface and for the Tc(CO) complexation.
