“…Semiconductor nanocrystals (quantum dots, QD) possess intense optical absorption in a wide spectral range and intensive and narrow fluorescence band, the position of which depends on QD core size [ 9 ]. Due to these extraordinary characteristics, QD can serve as an antenna, accumulating the light energy in a wide spectral region and passing it to other compounds, PPh, in particular [ 10 , 11 , 12 , 13 ].…”

The effect of bovine serum albumin (BSA) upon interaction between CdTe QD functionalized by 3-Mercaptopropionic Acid (CdTe-3-MPA QD) and two water soluble porphyrins: positively charged meso-tetra methyl pyridyl porphyrin (TMPyP) and negatively charged meso-tetrakis(p-sulfonato-phenyl) porphyrin (TPPS4), was studied in function of pH using the steady-state and time resolved optical absorption and fluorescence spectroscopies. It was shown that, depending on the charge state of the components, interaction with albumin could either prevent the formation of the QD…PPh complex, form a mixed QD…PPh…BSA complex or not affect PPh complexation with QD at all. The obtained results may be of interest for application in photomedicine.
