PG - 31-37 LID - S1089-8603(18)30274-X [pii] LID - 10.1016/j.niox.2019.01.016 [doi] AB - The light induced nitric oxide (NO) release properties of S-nitroso-N-acetylpenicillamine (SNAP) and S-nitrosoglutathione (GSNO) NO donors doped within polydimethylsiloxane (PDMS) films (PDMS-SNAP and PDMS-GSNO respectively) for potential inhaled NO (iNO) applications is examined. To achieve photolytic release of gas phase NO from the PDMS-SNAP and PDMS-GSNO films, narrow-band LED light sources are employed and the NO concentration in a N(2) sweep gas above the film is monitored with an electrochemical NO sensor. The NO release kinetics using LED sources with different nominal wavelengths and optical power densities are reported. The effect of the NO donor loading within the PDMS films is also examined. The NO release levels can be controlled by the LED triggered release from the NO donor-doped silicone rubber films in order to generate therapeutic levels in a sweep gas for suitable durations potentially useful for iNO therapy. Hence this work may lay the groundwork for future development of a highly portable iNO system for treatment of patients with pulmonary hypertension, hypoxemia, and cystic fibrosis.
