Abstract
A simple fluorescent strategy based on the formation of triple-helix molecular switch (THMS) between a signal transduction probe (STP) and an aptamer (Apt) was constructed for the determination of chloramphenicol (CAP). A weak fluorescence intensity was observed for STP solution due to the proximity of fluorophore and quencher through intramolecular DNA hybridization, causing the fluorescence quenching. The fluorescence intensity of the system was significantly enhanced after the addition of Apt. It was attributed to the formation of THMS between the Apt and STP through the Watson-Crick and Hoogsteen base pairing, resulting in the restoration of fluorescence because of the long distance between the fluorophore and quencher of STP. The fluorescence intensity of the system decreased due to the release of STP caused by the specific binding between Apt and CAP. The quantitative analysis of CAP could be achieved based on the decreased fluorescence intensity. The parameters affecting the performance of THMS including the Apt arm length, pH of buffer solution, Mg2+ concentration and the formation time of THMS were investigated in detail. Under the optimal conditions (Apt arm length of 9 bases, pH of 6.5, 2.5 × 103 μmol L-1 Mg2+, THMS formation time of 30 min), the decreased fluorescence intensity and the concentration of chloramphenicol were linear in the range of 5.0 × 10-3-2.0 × 10-1 μmol L-1 with the correlation coefficient of 0.9963. The limit of detection was 1.2 nmol L-1. Subsequently, the developed method was applied to the analysis of chloramphenicol in honey sample, and the recovery was between 84.5% and 103.0% with relative standard deviation less than 4.6%.

Abstract
Herein, an ultrasensitive and selective colorimetric assay for antibiotics, using chloramphenicol (CAP) as the model analyte, was developed based on magnetic aptamer-HRP-platinum composite probes and exonuclease-assisted target recycling. The composite probes were prepared through immunoreactions between the double stranded DNA antibody (anti-DNA) labeled on core-shell Fe3O4@Au nanoparticles (AuMNP-anti-DNA) as the capture probe, and the double stranded aptamer (aptamer hybrid with its complementary oligonucleotides) labeled on Pt@HRP nanoparticles as the nanotracer (ds-Apt-HRP-PtNPs). When the CAP samples were incubated with the probes for 30 min at room temperature, they could be captured by the aptamer to form a nanotracer-CAP complex, which was then released into the supernatant after magnetic separation. This is because the anti-DNA on the capture probes cannot recognize the single strand aptamer-CAP complex. The exonuclease I (Exo I) added into the supernatant can further digest the aptamer-CAP from the 3'-end of the aptamer and the CAP in the aptamer-CAP complex can be released again, which can further participate in a new cycling process to react with the probes. Pt and HRP in the nanotracer could both catalyze and dual amplify the absorbance at 650 nm ascribed to the 3,3',5,5'-tetramethylbenzidine (TMB)-H2O2 system. Moreover, Exo I can assist the target recycling, which can further amplify the signal. Thus, the triple amplified signal can be quantified by ultraviolet-visible spectroscopy. The experimental results showed that the CAP detection possessed a linear range of 0.001-10 ng mL(-1) and a detection limit of 0.0003 ng mL(-1) (S/N = 3). The assay was successfully employed to detect CAP in milk, which is much more facile, time saving, and sensitive than the commercial ELISA kits.
