Surface-enhanced immunoassay

The commercially available dicyanomethylene squaraine dye Seta-670-mono-NHS showed extremely low blinking effects and good photostability when used in single-molecule studies of multiple-fluorophore labeled antibodies [113]. Seta-670-mono-NHS and Seta-635-NH-mono-NHS were covalently labeled to antibodies and used in a surface-enhanced immunoassay [114]. From the fluorescence intensity and lifetime changes determined for a surface that had been coated with silver nanoparticles, both labeled compounds exhibited a 15- to 20-fold... [Pg.93]

Besides the methods given in Table 6-1 and Table 6-2, several others are available to determine dinitrophenols in biological and environmental samples. Immunoassay methods with sensitivities comparable to those of the conventional methods given in Tables 6-1 and 6-2 are noteworthy (Bush and Rechnitz 1987 Huang et al. 1992 Kusterbeck et al. 1990 Wannlund and DeLuca 1982). However, methods based on antibody sorption have not yet been validated on samples derived from environmental and biological sources, so it is not clear what methods of clean-up are necessary prior to quantitation of dinitrophenols. Some of the other detection methods with superior sensitivities that can determine dinitrophenols are surface-enhanced resonance Raman spectroscopy (Ni et al. [Pg.182]
