Preferential Tumor Accumulation of Polyglycerol Functionalized Nanodiamond Conjugated with Cyanine Dye Leading to Near‐Infrared Fluorescence In Vivo Tumor Imaging

In Scheme 1 of the originally published article, the chemical structure of Sulfo-Cy7-NHS ester was incorrect.The corrected scheme is shown below.Accordingly, the phrase "as expected from the four sulfonate (-SO 3 -) groups in Cy7 (Scheme 1)" in the left column in page 3 is corrected as "as expected from the two sulfonate (-SO 3 -) groups in Cy7 (Scheme 1)".The authors apologize for any misunderstanding this may have caused.
