Abstract

The photoluminescence (PL) spectrum of water-soluble thiol-capped CdTe quantum dots (QDs) conjugated with Tat peptide in solution showed a remarkable redshift as compared to that of unconjugated QDs. After cellular uptake of the Tat-QDs conjugates, the micro-PL spectrum of Tat-QDs in lysosomes showed a spectral blueshift, which was most probably due to the fact that Tat peptide was digested by the enzymes, leaving the Tat-detached QDs in lysosomes. The reasons for the spectral changes have been discussed in detail.
