Based on the experimental results the synthesized multifunctional nanodevices have the following structure and compositions: G5-(acetamide)96-(FITC)5-(Folic Acide)3-(Taxol)2, G5-( acetamide)96-(FITC)5-(Folic Acide)3-(Methotrexate(ester))2, G5-(acetamide)96-(FITC)5-(Folic Acide)3-(Methotrexate(amid))5, respectively. The delivery and targeting efficiency and cytotoxicity of the devices were tested in vitro on KB cell line.
