Analytical performance of the optical probes
To check the analytical performance of the probes in real
matrixes, the fructose content of a standard solution of fructose,
named high-fructose corn syrup 55 (HFCS-55) was determined
using the standard addition method. As expected, the NONB
probe was able to determine the fructose concentration of the
standard fructose sample successfully (the relative error was less
than 4.7% for three replicate measurements). This suggests that
this probe can potentially be used for quantitatively detecting
fructose levels in real samples like blood and urea.

Conclusions
In summary, we developed selective ‘‘turn-on’’ fluorescence
sensors for fructose detection by novel naphthalimide probes
based on photoinduced electron transfer. The photophysical
characteristics of the dyes were evaluated in the presence of
fructose. The probe including the amine moiety near the boron
atom revealed greater selectivity and sensitivity to fructose than
the probe including a sulfur moiety. The remarkable enhance-
ment in the fluorescence intensity of the NONB probe upon the
addition of fructose makes it potentially a good candidate for
fabricating a highly sensitive and selective probe for quantita-
tively detecting fructose levels in real samples such as blood
and urea.
