Recent developments in tumour treatment had focused on virotherapies that were currently revolutionising new innovated treatment pathways. This study focused on the fabrication of oncolytic adenoviral vector (Ad) nanosphere that self-targeted at lung tumour cells (A549), utilising the immune response for upper respiratory tract infection, caused by the Ad infection. This system was dependent upon T-cell immune response, surface charge and blood metabolism. Oncolytic Ad attacked lung A549 tumour cells by incorporated its own DNA to replace A549's, the triggered immune response generated T-cells also further attack A549. Direct Ad injection was demonstrated to be lethal and prohibited in vivo. In this research a multifunctional principal using polyprotein surface precipitation technique (PSP) whist maintaining biological controls for self-assembly polyprotein Ad nanosphere both biocompatible and reproducible, was demonstrated as a result of the enhanced transfection efficiency and a successful multifunctional drug delivery system for virotherapy.
