Previously, we showed that nanostructures 1/2 reduced the exogenous EGFR level by more than 60% at a concentration of 200 nM after 48 h using DFA (EGFR-EGFP/RFP dual fluorescence assay) performed in MCF-7 (breast cancer), A431 (squamous carcinoma), and HeLa (cervical carcinoma) cells [35]. This evidence concerns the gene EGFR and squamous cell carcinoma.
