“…For example, potentiometric sensor-incorporated neutral β -CD was able to enhance the sensitivity and selectivity of electrodes in ion molecules, especially naproxen [14]. β -CD attached to a lactone ring on the primary side of the CD also showed a large affinity to bile acids by the interaction between the chromophore unit and the guest molecule in the complex [15]. A forchlorfenuron-imprinted polymer utilizing β -CD as a monomer had better recognition and reversibility to forchlorfenuron [16].…”

It has been increasingly important to develop a highly sensitive and selective technique that is easy to handle in detecting levels of beneficial or hazardous analytes in trace quantity. In this study, mono-6-deoxy-6-aminopropylamino-β-cyclodextrin (pr-β-CD)-functionalized silver-assembled silica nanoparticles (SiO2@Ag@pr-β-CD) for flavonoid detection were successfully prepared. The presence of pr-β-CD on the surface of SiO2@Ag enhanced the selectivity in capturing quercetin and myricetin among other similar materials (naringenin and apigenin). In addition, SiO2@Ag@pr-β-CD was able to detect quercetin corresponding to a limit of detection (LOD) as low as 0.55 ppm. The relationship between the Raman intensity of SiO2@Ag@pr-β-CD and the logarithm of the Que concentration obeyed linearity in the range 3.4–33.8 ppm (R2 = 0.997). The results indicate that SiO2@Ag@pr-β-CD is a promising material for immediately analyzing samples that demand high sensitivity and selectivity of detection.
