In the original article, there was a mistake in Figure 9E, panel d as published. Figure 9E has been redrawn and the corrected Figure 9E appears below.
FIGURE 9
In the original article, there was an error in section two, Experimental Section, whereby several descriptions for the preparation of nanocomposites CD-PAMAM-Arg8 and CD-PAMAM-Arg8/Dex were omitted.
The following correction should be made to Experimental Section, “2.2.3 Preparation of Nanocomposites With Drugs”, paragraph 1:
“Arg8 polypeptides (lipid concentration: 1.5 mg/ml), EDC (lipid concentration: 0.2 mg/ml), and NHS (lipid concentration: 0.4 mg/ml) were added into PBS (pH = 7.4) and stirred at room temperature for 4 h. The drug-loaded nanomaterial powder (Au @CD-PAMAM) was dissolved in PBS, and then the commixture of the two solutions was obtained and allowed to react overnight at room temperature. The mixture was freeze-dried to obtain the drug-loaded nanocomposite material with targeted properties of Au @CD-PAMAM-Arg8(Au-DENPs). The free chemical residues were removed by dialysis using a 1-kDa MWCO membrane. Dexamethasone (Dex) dissolved in DMSO (concentration: 2 mg/ml) was added to the Au-DENPs. The mixed solution was stirred overnight at room temperature, filtrated with a 2-kDa MWCO membrane and freeze-dried to get Au @CD-PAMAM-Arg8/Dex (Au DENPs-Dex).”
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
