In SituNitric Oxide (NO) Measurement by Modified Electrodes: NO Labilized by Photolysis of Metal Nitrosyl Complexes

Photo-Controlled Release of NO and CO with Inorganic and Organometallic Complexes

“…Among these is sodium nitroprusside Na 2 [Fe(CN) 5 NO], which has long been used therapeutically as a vasodilator during hypertensive emergencies [69]. Although photoactive [70,71], nitroprusside can also release NO thermally upon contact with tissue containing reducing species thereby limiting the photochemical control over the release of NO in this case.…”

Gold nanoparticle modifies nitric oxide release and vasodilation in rat aorta

“…The sensitivity of this apparatus ranges between 1 nmol/L and 20 μmol/L, with a 2-mm sensor, which directly detects NO concentration by amperometric technique. The setup was calibrated following the procedure previously reported [22][23][24]. The recordings were performed in organ chamber with aortic rings in Krebs solution maintained at pH 7.4 gassed with 95 % O 2 and 5 % CO 2 at 37°C under ambient light to guarantee similar conditions of the functional studies.…”

Visible‐Light‐Triggered Release of Nitric Oxide from N‐Pyramidal Nitrosamines

“…The fluorescence intensity of DAF-2-T was converted to concentration of NO on the basis of the calibration curve method: an aliquot of a stock solution of DAF-2 in DMSO (40 mL, 5 mm) and DMSO (320 mL) were diluted by adding PBS buffer (20.44 mL, pH 7.4; PBS-DMSO (containing 1.7 % DMSO)). An aliquot of saturated PBS stock solution (2.5, 5.0, 10, or 20 mL, 1.9 mm) of NO (gas) [15] was added to an aliquot of the above DAF-2 solution (2600 mL, 9.62 mm) in a glass vial equipped with a magnetic stirrer. The final concentrations of NO were 1.9, 3.8, 7.6, and 15.2 mm, respectively.…”
