RNPC3 and neoplasm: reported multifunctional NPs for RNP controlled release.[112] A nitrilotriacetic acid decorated NPs were loaded with Ce6 photosensitizer, captured the his‐tagged Cas9 RNP, and coated with a cationic iRGD‐PEGylated polymer to construct multifunctional NPs for integrin‐mediated targeted RNP delivery into tumor cells.
