Small 2019, 15, 1901930 In Scheme 1 of the originally published article, the chemical structure of Sulfo-Cy7-NHS ester was incorrect. The corrected scheme is shown below. 1 Scheme (Figure presented.) Synthesis of ND-PG-Cy7 through the conjugation of Cy7 with ND-PG-NH2. Accordingly, the phrase “as expected from the four sulfonate (–SO3−) groups in Cy7 (Scheme 1)” in the left column in page 3 is corrected as “as expected from the two sulfonate (–SO3−) groups in Cy7 (Scheme 1)”. The authors apologize for any misunderstanding this may have caused.
