Plasmonic nanoprobes for real-time optical monitoring of nitric oxide inside living cells.
An optical sensor was developed for the quantitative determination of intracellular nitric oxide. The sensor consists of plasmonic nanoprobes that have a coating of mesoporous silica and an inner gold island film functionalized with a chemoreceptor for NO.
