NO hiding from this sensor: Reversible binding of nitric oxide to an iron(III) corrole induces spectral changes close to the Soret absorption band, thus enabling photometric nitric oxide detection (see figure). Sensitive photometric detection in the picomolar range was possible using this amphiphilic iron(III) corrole. The amphiphilicity allows for self-assembly of the complex into thin solid films, which will be developed for sensing applications.
