Electrical conduction in some nucleic acid base complexes with acridine orange dye: study of localized levels.

abstract：:DNA that encodes tumor-specific antigens represents potential immunostimulatory agents. However, rapid enzymatic degradation and fragmentation of DNA during administration can result in limited vector expression and, consequently, poor efficacy. These challenges have necessitated the use of novel strategies for DNA de...
