“…This analysis also gives insight into the binding capacities of matrix and template. Reports have presented cases where it was used to characterize substances like benzotriazole [ 44 ], tetracycline [ 45 ], b-estradiol, estradiol benzoate, ethynyl estradiol etc. [ 46 ], as well as the extent to which binding was feasible.…”

This study reports the feasible use of chitosan as a thin film biosensor on the very sensitive quartz crystal micro balance system for detection of blends of multiple templates within a single matrix. The development of chitosan-based thin film materials with selectivity for nicotine derivatives is described. The molecular imprinting of a combination of nicotine derivatives in N-diacryloyl pipiradine-chitosan-methacrylic acid copolymer films on quartz crystal resonators was used to generate thin films with selectivity for nicotine and a range of nicotine analogues, particularly 3-phenylpyridine. The polymers were characterized by spectroscopic and microscopic evaluations; surface area, pore size, pore volume using Breuner-Emmet-Teller method. Temperature characteristics were also studied. The swelling and structure consistency of the Chitosan was achieved by grafting with methylmethacrylic acid and cross-linking with N-diacrylol pipiradine. A blend of 0.002 g (0.04 mmol) of Chitosan, 8.5 μL Methylmethacrylic Acid and 1.0 mg N-diacrylol pipradine (BAP) presented the best blend formulation. Detections were made within a time interval of 99 sec, and blend templates were detected at a concentration of 0.5 mM from the Quartz crystal microbalance resonator analysis. The successful crosslinking of the biopolymers ensured successful control of the swelling and agglomeration of the chitosan, giving it the utility potential for use as thin film sensor. This successful crosslinking also created successful dual multiple templating on the chitosan matrix, even for aerosolized templates. The products can be used in environments with temperature ranges between 60 °C and 250 °C.

We all are surrounded by millions of bacteria, and antibiotics are the only medicine that exists on the Earth to protect us from the thousands of bacterial infections. However, excess consumption of these antibiotics has accelerated the bacterial resistance process. The resistive bacteria then spread and grew exponentially and created several health problems. So, a system is necessarily required that smartly detects the presence of antibiotics in the contaminated samples. Here in this work, a carbon quantum dots (CQDs) based fluorescence resonance energy transfer (FRET) "Turn-Off" sensor was developed for tetracycline (Tetra) detection in animal-derived food samples. The highly fluorescent CQDs have average particle size of around 1.80 ± 0.435 nm were synthesized using pyrolysis method. Here, CQDs-Tetra form a FRET pair, and the emission intensity of CQDs reduced to 57. 3% in the presence of Tetra due to the transfer of energy from donor (CQDs) to acceptor (Tetra). Further, analyzing the lifetime decay of CQDs, which changed from 9.43 ns to 8.89 ns with addition of Tetra, confirms the FRET quenching mechanism. The sensor show the linear response with Tetra concentration varies as 0.05−100 μM with a limit of detection 10.47 nM. The applicability test of the sensor was carried out with real milk and egg samples spiked with standard concentration of Tetra. The test results proved that the sensor could be used as a food monitoring tool.
