Decomposition kinetic study of diazeniumdiolates within polymer HMwPEI/NO (5) as measured via UV in 100 mM deoxygenated phosphate buffer (0.1 mg/mL, pH 7.4) at 26 °C; each spectrum was collected at a 10 min interval. Inset: Plot used to determine a near-first-order rate constant of k_D=3.9×10⁻⁵ s⁻¹ (each absorbance data was collect at λ=250 nm with an interval of 15 s).
