The article "Supramolecular Chemistry on Water-Soluble Carbon Nanotubes for Drug Loading and Delivery" by Zhuang Liu, Xiaoming Sun, Nozomi Nakayama-Ratchford, and Hongjie Dai (ACS Nano 2007, 1, 50–56) includes corrections to the molar extinction coefficients used in the study. Specifically, the molar extinction coefficient for doxorubicin should be 1.05 × 10⁴ M⁻¹·cm⁻¹ instead of 1.05 × 10⁵ M⁻¹·cm⁻¹. These corrections are made in the text on page 54, right column, last paragraph. Additionally, the article "Hetero-apertured Micro/Nanostructured Ordered Porous Array: Layer-By-Layered Construction and Structure-Induced Sensing Parameter Controllability" by Lichao Jia, Weiping Cai, Hongqiang Wang, Fengqiang Sun, and Yue Li (ACS Nano 2009, 3, 2697–2705) includes an erratum for Figure 8b, which should be replaced with a corrected diagram. Lastly, the article "Quantum Dot Peptide Biosensors for Monitoring Caspase 3 Proteolysis and Calcium Ions" by Duane E. Prasuhn, Anne Feltz, Juan B. Blanco-Canosa, Kimihiro Susumu, Michael H. Stewart, Bing C. Mei, Aleksey V. Yakovlev, Christina Loukou, Jean-Maurice Mallet, Martin Oheim, Philip E. Dawson, and Igor L. Medintz (ACS Nano 2010, 4, 5487–5497) corrects a misspelling in the author list, where "Loukov" should be "Lukou."The article "Supramolecular Chemistry on Water-Soluble Carbon Nanotubes for Drug Loading and Delivery" by Zhuang Liu, Xiaoming Sun, Nozomi Nakayama-Ratchford, and Hongjie Dai (ACS Nano 2007, 1, 50–56) includes corrections to the molar extinction coefficients used in the study.
