Abstract A general strategy to carry out cell uptake and biodistribution studies is label nanoparticles (NPs) with a fluorescent dye. However, the comparative study of different dye‐loaded NPs remains difficult owing uncontrolled dye quenching de‐quenching. Here we compared two types dye‐labeled demonstrated their distinct properties. molecules at solid state suffer from quenching, so release and/or NP degradation in biological environments leads several‐fold increase fluorescence intensity despite same amount NPs, switch In contrast, soluble exhibit no effect. To standardize study, propose possible solutions: using lower loading or medium analysis for quantifying NPs. This work provides valuable insights into selecting valid quantification methods bio‐nano studies.
