Catalyst-Free Conjugation and In Situ Quantification of Nanoparticle Ligand Surface Density Using Fluorogenic Cu-Free Click Chemistry
Publication: Research - peer-review › Journal article – Annual report year: 2011
A highly efficient method for functionalizing nanoparticles and directly quantifying conjugation efficiency and ligand surface density has been developed. Attachment of 3-azido-modifed RGD-peptides to PEGylated liposomes was achieved by using Cu-free click conditions. Upon coupling a fluorophore is formed, which could be utilized to monitor conjugation efficiency and the obtained ligand surface density in situ, without prior purification.
