Show Abstract |
|||||||||||||||||||||||||||||||||||||
A sandwich-type analytical sensor device for the determination of fluoride in aqueous samples was developed. The device is based on a versatile sandwich design, consisting of a molecularly imprinted polymer layer confined between two material layers. One layer is transparent to UV radiation while the other allows the passage of the analyte. The imprinted polymer, previously reported by our team, presents an increase on its fluorescence that correlates with the concentration of fluoride. Analytical parameters such as limit of detection (LOD), limit of quantification (LOQ), linear range, repeatability, and accuracy were quantified to evaluate the device's performance. Furthermore, the sensor's response to interfering substances, such as phosphate and chloride, was assessed. With promising performance characteristics, this sandwich-type sensor demonstrates potential for application in diverse sample matrices, including industrial, environmental, and other relevant aqueous samples for fluoride analysis. |

Show Abstract |
|||||||||||||||||||||||||||||||||||||
There is a growing need for portable, highly sensitive measuring equipment to analyze samples in-situ and in real time. For these reasons, it is becoming increasingly important to research for new experimental equipment to carry out this work with advanced, robust and low-cost devices. In this framework, a flexible, portable and low-cost fluorimeter (under 500€) based on a C12880MA MEMS micro-spectrometer with an Arduino compatible breakout board has been developed for trace analysis of biological substances. The proposed system can employ two selectable excitation sources for flexibility, one in the visible region at 405 nm (incorporated in the board) and an external LED at 365 nm in the UV region. This additional excitation source can be easily interchanged varying the LED type for other wavelengths of interest. The measurement process is micro-controlled, which allows a precise control of the spectrometer sensitivity by adjusting the integration time of each experiment separately. Data acquisition is easy, reliable and interfaced with a spreadsheet for fast spectra visualization and calculations. For testing the performance of the new device in fluorescence measurements, different fluorophore molecules which can be commonly found in biological samples, such as Fluorescein, Riboflavin, Quinine, Rhodamine b and Ru(II)-bipyridyl have been employed showing a high sensitivity in all cases and low quantitation limits (in the ppb range). It is also suitable for the study of other interesting phenomena, such as fluorescence quenching induced by chemical agents (such as halide anions or even auto-quenching). In this sense, an application for the chloride anions quantification in aqueous solutions, has been performed obtaining a LOD value of 18 ppm. Obtained results for all chemicals investigated with the proposed fluorimeter are always very similar in quantification figures or even better than literature data reported with commercial laboratory equipment |

sciforum-076640 | One step electrodeposition of multi-walled carbon nanotubes-chitosan for Quaternary Ammoniums Compounds biosensor | , , | N/A | N/A |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Quaternary Ammoniums Compounds (QACs) are biocide disinfectants used in the food industry to decontaminate and prevent the spread of infection. For example, milk tanks can be decontaminated with benzalkonium chloride (BAC) and/or dimethyldidecylammonium chloride (DDAC). The presence of QAC residues in rinsing water after cleaning and disinfection procedures and in milk products is monitored in industry with commercial tests, which are not sensitive enough. An enzymatic sensor for the detection of QACs was obtained for the first time. We have developed a simple electrochemical method for the immobilization of acetylcholinesterase (AChE). It was based on the covalent bonding of AChE to a multiwall carbon nanotube (c-MWNT)-cross-linked chitosan (Chi) modified glassy carbon screen-printed electrode (SPE) [1]. The AChE activity was inhibited in the presence of QACs, which induced a change in the measured current. The native structure of the immobilized enzyme AChE was preserved on this composite film, because of the excellent biocompatibility and non-toxicity of chitosan. This film was elaborated by one-step electrodeposition on a glassy carbon screen-printed electrode (GC). Incorporation of functionalized multiwalled carbon nanotubes (c-MWCNT) into a chitosan film promoted electron transfer reaction and enhanced the electrochemical response. Glutaraldehyde (GA) was used as cross-linker to covalently bind the AChE, and efficiently prevented leakage of the enzyme from the film. A sensitive voltammetric sensor was optimized for the rapid detection of QACs (eg. DDAC) in milk [2]. This biosensor is a promising new tool for QACs analysis.

Colorimetric and fluorimetric fingerprinting techniques have gained popularity in solving various practical tasks associated with recognition and discrimination of samples. An underdeveloped aspect of optical fingerprinting methods is the use of kinetic factor that can serve as an additional variable. For the recognition of each type of sample we propose to select an indicator reaction whose rate is sensitive to the small variations in the composition of the sample. The samples and reactants are mixed in the 96-well fluorimetric plates, after which absorbance and fluorescence of the wells is registered photographically every several minutes. After digitization, the results are subjected to chemometric processing. For the recognition of 8 model proteins or 10 samples of rennet enzymes, pre-oxidation of the sample with hypochlorite was suggested, and then a carbocyanine dye was added as reductant. For the recognition of motor oils, a set of reactions occurring in ethanol was proposed, and the reaction of oxidation of a commercial carbocyanine dye with nitric acid permitted to completely discriminate 6 oils. For the estimation of the doses absorbed by irradiated food (potatoes, ground beef), oxidation reactions of several carbocyanine dyes with hydrogen peroxide were used, which allowed for confident recognition of the dose to an order of magnitude (0, 100, 1000, 10,000 Gy). The proposed reaction-based approach turned out to be a powerful technique for solving various recognition tasks. |

Show Abstract |
|||||||||||||||||||||||||||||||||||||
Gas sensors, such as chemoresistors and functionalized quartz microbalances and other types, often exhibit limited selectivity, necessitating their integration into sensor arrays. Through the utilization of statistical analysis techniques, these arrays can collectively provide enhanced selectivity. However, it is important to note that the selectivity achieved by electronic noses is artificial in nature. Consequently, despite their ability to discriminate between different samples, electronic noses do not provide insights into the specific gases or volatile organic compounds (VOCs) being detected. This inherent limitation poses challenges in understanding the precise analytes detected by electronic noses, further emphasizing the need for complementary analytical techniques to identify and characterize specific gas or VOC targets. Proton transfer reaction mass spectrometry (PTR-MS) is a powerful and fast analytical technique that can be used simultaneously with sensors to help understand which molecules they are detecting. In addition to this reference technique role, PTR-MS can also be used to better understand the sampling process and thus optimize it. |
