Manipulation of silver nanocubes detection sensitivity to radical compounds by modifying their surfaces with anionic/cationic polyelectrolytes for wide-range quantification of radicals.

We report a method for controlling the detection sensitivity to or the degree of etching of Ag nanocubes by radicals by modifying their surfaces with poly(acrylic acid) or poly(allylamine hydrochloride) for wide-range quantification of radical compounds. The degree of Ag nanocube etching is influenced by the concentrations of the polyelectrolytes used for… (More)
