Abstract
Abstract
We report on fluorescence quenching experiments of CdSe quantum dots,
which were encapsulated for biocompatibility using different
strategies. Since their fluorescence is very sensitive against water
and other quenching molecules reaching their surface, quenching
experiments allow conclusions on particle shielding towards the
surrounding medium. It turns out that best shielded particles with
comparable chemical composition of their ligand shell have also
outstanding properties in respect of undesired unspecific cellular
uptake.
