Abstract
Correction for ‘Time-resolved infra-red studies of photo-excited porphyrins in the presence of nucleic acids and in HeLa tumour cells: insights into binding site and electron transfer dynamics’ by Páraic M. Keane et al., Phys. Chem. Chem. Phys., 2022, 24, 27524–27531, https://doi.org/10.1039/D2CP04604K.
The TRIR spectrum given in panel b of Fig. 2 in the published version of the manuscript is incorrect. The correct figure is shown below.
 | ||
| Fig. 1 TRIR spectra at 3 (red), 10 (blue), 50 ps (black) for 500 μM PtTMPyP4 in the presence of nucleic acids (a) 10 mM GMP, (b) 500 μM {d(GC)5}2, (c) 500 μM {d(CGCAAATTTGCG)}2, (d) c-MYC quadruplex. In buffered (50 mM phosphate pH 7, c-MYC also with 70 mM KCl, D2O). λexc = 400 nm (0.25–1 μJ). Regions of nucleotide absorption are highlighted and spectra are normalised to the 1636 cm−1 transient. | ||
