Caption Researchers developed DNA-based fluorescent sensors that can detect two different forms of iron (Fe2+ and Fe3+) at the same time in cell cultures and in brain slices from mice genetically ...

But part of what makes the Nikon FE, FE2, FM and FM2 so desirable is their rock-solid build quality. The less complicated a camera is, the less there is to go wrong.

IntroductionDilute solutions of Fe (NCS)2+ have their equilibrium positions shifted with the addition of Fe (NO3)3, KSCN, NaOH, and AgNO3.*There is no prep box for this demo in the demo room.

Iron articles from across Nature Portfolio Iron (Fe, atomic number 26) is a redox-active transition metal element found in living systems as Fe2+ or Fe3+ ions. It is rarely found free in biology ...
