Novel Polyethylene Glycol Derivatives of Melatonin and Serotonin. Ligands for Conjugation to Fluorescent Cadmium Selenide/Zinc Sulfide core shell Nanocrystals

This paper describes the synthesis and characterisation of derivatives of melatonin and serotonin that may be attached to highly fluorescent cadmium selenide/zinc sulfide core shells nanocrystals for use in biological assays and fluorescence imaging applications.
