英文摘要	in-fibre chemical and optical sensors based on silver nanocrystals modified microstructured polymer optical fibres (mpofs) were demonstrated. the silver nanocrystals modified mpofs were formed by direct chemical reduction of silver ammonia complex ions on the templates of array holes in the microstructure polymer optical fibres. the nanotube-like and nanoisland-like ag-modified mpofs could be obtained by adjusting the conditions of ag-formation in the air holes of mpofs. sem images showed that the higher concentration of the reaction solution (silver ammonia 0.5 mol/l, glucose 0.25 mol/l), gave rise to a tubular silver layer in mpof, while the lower concentration (silver ammonia 0.1 m, glucose 0.05 m) produced an island-like ag nanocrystal modified mpof. the tubular ag-mpof composite fibre was conductive and could be directly used as array electrodes in electrochemical analyses. it displayed high electrochemical activity on sensing nitrate or nitrite ions. the enhanced fluorescence of dye molecules was observed when the island-like ag-modified mpof was inserted into a fluorescent dye solution.
