Real-time and indicator-free detection of aqueous nitric oxide with hydrogel film
2010
Applied Physics Letters
Preserved Fulltext
A sensing hydrogel film is demonstrated for real-time and indicator-free detection of nitric oxide ͑NO͒ in aqueous solution. The film composed of NO probe 11,16-bisphenyl-6,6,21,21tetramethyl-m-benzi-6,21-porphodimetheno-chloro-zinc͑II͒ and host polymer poly͑2-hydroxyethyl methacrylate͒. The water-containing nature of this sensing hydrogel film makes the surface area high. The response time is bellow 10 s. This sensing hydrogel film also shows high selectivity, sensitivity, and stability in various pH values.
