The present study focuses on the conjugation of gold nanorods (GNRs) with gentamicin via the Nanothink acid linker and its application in delivery of gentamicin to infection foci due to Staphylococcus aureus. 
Nanothink
The interaction between gentamicin and gold nanorods was confirmed by FT-IR spectroscopy. 
FT-IR spectroscopy
The high performance liquid chromatography (HPLC) and atomic absorption spectroscopy analyses showed that 2050 gentamicin molecules were attached to each gold nanorod.
