title: An operationally simple colorimetric assay of hyaluronidase activity using cationic gold nanoparticles.
abstract: An operationally simple colorimetric way for measuring hyaluronidase activity was developed using cysteamine-bound gold nanoparticles. The addition of gold nanoparticles into hyaluronidase-containing solutions resulted in color changes, which could easily be observed with the naked eye or a UV/Vis spectrophotometer.
