Abstract
A new fluorescence strategy was described for ratiometric sensing of formaldehyde (FA) with bifunctional MOF, which acted as a fluorescence reporter as well as biomimetic peroxidase. With the assistance of H2O2, NH2-MIL-101 (Fe) catalyzes the oxidation of non-luminescent substrate o-phenylenediamine (OPD) to produce fluorescent product (oxOPD) with the maximum emission at 570 nm. Besides, intrinsic fluorescence of MOF (λem = 445 nm) was quenched by oxOPD through inner filter effect (IFE). However, FA and OPD reacted to generate Schiff bases, which competitively consumed OPD inhibiting the generation of oxOPD. Under the excitation wavelength of 375 nm, a ratiometric strategy was designed to detect FA with the fluorescence intensity ratio at 445 nm and 570 nm (F445/F570) as readout signal. This strategy exhibited a wide linear range (0.1-50 μM) and low detection limit of 0.03 μM. This method was confirmed for FA detection in food samples. In addition to establishing a new method to detect FA, this work will open new applications of MOF in food safety.

Abstract
Background:
Formaldehyde is widely acknowledged as a carcinogen, but as an important
organic reagent, it has also been widely employed in the fields of chemical synthesis, industrial production
and biomedicine. It is therefore of great practical significance for the detection of formaldehyde in
food, clothing, daily necessities, construction materials and environments.
Methods:
The two silicon QDs, that are, DAMO-Si-QDs (with N-[3-(Trimethoxysilyl) propyl]
ethylenediamine as silicon source) and APTMS-Si-QDs (with (3-Aminopropyl) trimethoxysilane as
silicon source) as the fluorescence probe to detect formaldehyde in both water and organic phases.
Results:
Silicon QDs prepared by different silicon sources exhibit an obvious difference in their tolerances
to the environment and the responses to formaldehyde. However, APTMS-Si-QDs show better
selectivity in both water and organic phases. In Tris-HCl solution (20.00mmol•L-1, pH=5), the formaldehyde
concentration maintains an excellent linear relationship with the fluorescence intensity of
APTMS-Si-QDs in the range of 3.125×10-7-3.125×10-5 mol•L-1, with correlation coefficient R2=
0.9998. In methanol, the formaldehyde concentration maintains an excellent linear relationship with the
fluorescence intensity of APTMS-Si-QDs in the range of 1.563×10-7-3.125×10-5 mol•L-1, with correlation
coefficient R2= 0.9992.
Conclusion:
It is found that DAMO-Si-QDs show poor response to the presence of formaldehyde,
while APTMS-Si-QDs got a strong, sensitive and selective response to that in both aqueous and organic
phases. In the Tris-HCl buffer (20 mmol•L-1, pH=5), the linear range for formaldehyde detection reaches
3.125×10-7-3.125×10-5 mol•L-1, and for the detection in the organic phase, the linear range reaches
1.563×10-7-3.125×10-5 mol•L-1, in methanol solution. The paper provides a sensitive, selective and simple
means for formaldehyde detection in both aqueous and organic phase
