The invention provides a mild procedure for the functionalization of cellulose and other substrates with a detection reagent such as N-(1-naphthyl)ethylenediamine and is able to achieve much higher functionalization density than previously reported. A paper-based device created using cellulose functionalized according to the invention allowed for much lower detection limits for nitrite in various kinds of water samples than have been seen using paper-based devices. In addition, grafting of N-(1-naphthyl)ethylenediamine to cellulose improved the stability of the N-(1-naphthyl)ethylenediamine in the presence of moisture and light.

Disclosed is a method for visually identifying quality of Lilii Bulbus, including: uniformly mixing an extracting solution of a Lilii Bulbus sample to be detected with gold-silver nanoclusters, standing the mixed extracting solution for reaction, and realizing visual identification of Lilii Bulbus quality according to information of color or information of fluorescence intensity of a detection system obtained after the reaction and response difference of the color or fluorescence of Lilii Bulbus samples with different quality. Compared with that existing detection method based on chromatography and the like, the method provided by the present application has the advantages of high stability, fast response, easy operation and portable devices in addition to a broad application prospect for industrial production.
