Conventional chemical modifications of single-stranded ASO (ssASO) do not have a significant impact on the free energy. 
=> These thermodynamic relations (= molecular-interactions) remain largely unchanged.
Reducing the free energy of ASO with a complementary strand can significantly change the molecular interaction landscape. 
A novel kinetic mechanism utilizing TMSD (Toehold Mediated Strand Displacement) to promote the formation of desired products.
