NO has a short half-life in vivo... some have measured 1 s, .9-2 s and such. It stimulates vasodilation reportedly by endothelial production (the inner lining of the blood vessels spraying NO at the blood vessel smooth muscle to induce relaxation). Red blood cells with their high hemoglobin content facilitate a high degree of NO scavenging. Auto-oxidation with O2 is reported to be rather slow and somewhat unimportant. Additionally, there are degredation mechanizms as previously mentioned in this thread that do take care of the reactive nitrogen species production.

Is, but it just seems to hate water. We need it to be a hydrated material.

Im looking for a material that can achieve a moldable, low viscosity liquid phase and then solidify into the shape i want. It has to be transparent, able to absorb... or hold... water, highly gas permeable, and biologically inert. We've experimented with Nafion, various RTV Silicone rubbers, and agarose. Anyone have anything else that might come to mind? Just looking to broaden horizons here

Go to doctor. You may not have diabetes, but your abnormal water intake may be making you hypertensive. You mentioned "blurred vision." Though high blood pressure might just be a symptom of whatever is causing your thirst, its something that shouldnt be fooled around with. Freakin hitup the dr and you'll be better off. Well unless someone sneezes on you in the office...

Figured about the UV, but unless Chroma has been tellin it wrong, the filters we are using have maximum excitation around 490 nm and emission is usually 540... The graphs of these indicate that there should be no UV component. Additionally, the only organic component we have used so far is the dye itself. So does visible light have a UV-like ability to produce singlet oxygen?

Hey, first time post so take it easy on my noobishness Wasn't exactly sure if this should go under chemistry or physics considering that im a biologist so i just chucked it here. We know that molecular oxygen (O2) quenches fluorescent species. We are observing light-dependent rises in fluorescence (we've controlled for more light more F) that have been attributed to a reduction in the solution's [O2]. My question is kinda simple, knowing little about it, does light produce singlet oxygen from O2? Haven't started drinkin yet so my google searches have lacked creativity thus far.
