a
Time required to reach maximum NO flux.
b
Half-life for NO-release from PU films.
c
Nitric oxide release was below the limit of detection of the NOA.
d
Total amount of NO released.
e
Measured by irradiation of the sample flask with 200 W light.
f
Determined at the time at which 99% of the total NO was released.
