Colloidal nanoparticles carrying double-stranded DNAs on their surfaces undergo dispersion only when a terminal single-base mismatch exists at the interface between a DNA-shell and bulk. Based on the drastic change of colloidal stability, we developed a facile method to evaluate the thermal stability of a non Watson-Crick base pair between an oxidative-damaged guanine (8-oxoG) and each four natural nucleobase.
