ACS Sensors, Год журнала: 2024, Номер 9(2), С. 555 - 576

Опубликована: Фев. 2, 2024

Sensitive, accurate, and reliable detection of explosives has become one the major needs for international security environmental protection. Colloidal quantum dots, because their unique chemical, optical, electrical properties, as well easy synthesis route functionalization, have demonstrated high potential to meet requirements development suitable sensors, boosting research in field explosive detection. Here, we critically review most relevant works, highlighting three different mechanisms based on colloidal namely photoluminescence, electrochemical, chemoresistive sensing. We provide a comprehensive overview an extensive discussion comparison terms sensor parameters. highlight advantages, limitations, challenges dot-based sensors outline future directions advancement knowledge this surging field.

A ratiometric fluorescence probe for bisulfite detection in live cells and meat samples

Methods, Год журнала: 2024, Номер 225, С. 100 - 105

Опубликована: Март 31, 2024

The development of reliable probe technology for the detection bisulfite (HSO3-) in situ food and biological samples is contributing significantly to quality safety assurance as well community health. In this work, a responsive probe, EHDI, developed ratiometric fluorescence HSO3- aqueous solution, meat samples, living cells. designed based on triggered 1,4-addition electron deficit C = bond EHDI. As result specific 1,4-addition, π-conjugation system was destructed, resulting blue shifts emission from 687 440 nm absorption 577 355 nm. has good water solubility, high sensitivity selectivity, allowing it be used imaging internalization production endogenously. capability EHDI then validated by traditional HPLC technology, enabling accurately detect beef samples. successful thus offers new tool investigating conditions.

Liquid phase detection in the miniature scale. Microfluidic and capillary scale measurement and separation systems. A tutorial review

Analytica Chimica Acta, Год журнала: 2024, Номер 1305, С. 342507 - 342507

Опубликована: Март 23, 2024

Microfluidic and capillary devices are increasingly being used in analytical applications while their overall size keeps decreasing. Detection sensitivity for these microdevices gains more importance as device sizes consequently, sample volumes, decrease. This paper reviews optical, electrochemical, electrical, mass spectrometric detection methods that applicable to scale microfluidic devices, with brief introduction the principles each case. Much of this is considered context separations. We do consider theoretical aspects separations by open tubular liquid chromatography, arguably most potentially fertile area has been left fallow largely because lack scale-appropriate methods. also examine basis zone electrophoretic Optical discussed include UV/Vis absorbance, fluorescence, chemiluminescence refractometry. Amperometry essentially only electrochemical method microsystems. Suppressed conductance especially contactless conductivity (admittance) wide use ionic analytes. integrated various spectrometers, including ESI-MS, APCI-MS, MALDI-MS discussed. advantages disadvantages compare best reported limits uniform a format available information allows. While review pays attention recent developments, our primary focus on novelty ingenuity approach, regardless when it was first proposed, long can be relevant miniature platforms.
