“…So, direct introduction of the macrosize (subgram or gram level) sample inevitably results in a lot of matrix interference. To overcome the matrix interference, the online gas phase enrichment (GPE) technique such as gold amalgamation, 220,228 tungsten coil trap, 217,227,229,231 and quartz trap 222,232 was utilized to preconcentrate target elements to separate from interferents in addition to normal strategies such as matrix matching, standard addition calibration, or chemical modifier. On the other hand, microsampling analysis is another important application via introducing microsample sizes such as the 240,241 a stronger capacity of simultaneous multielements and isotopic analysis can be fulfilled to investigate elemental metabolism in the microsample.…”

Agrometallomics, as an independent interdiscipline, is first defined and described in this review. Metallic elements widely exist in agricultural plants, animals and edible fungi, seed, fertilizer, pesticide, feedstuff, as well as the agricultural environment and ecology, and even functional and pathogenic microorganisms. So, the agrometallome plays a vital role in molecular and organismic mechanisms like environmetallomics, metabolomics, proteomics, lipidomics, glycomics, immunomics, genomics, etc. To further reveal the inner and mutual mechanism of the agrometallome, comprehensive and systematic methodologies for the analysis of beneficial and toxic metals are indispensable to investigate elemental existence, concentration, distribution, speciation, and forms in agricultural lives and media. Based on agrometallomics, this review summarizes and discusses the advanced technical progress and future perspectives of metallic analytical approaches, which are categorized into ultrasensitive and high-throughput analysis, elemental speciation and state analysis, and spatial- and microanalysis. Furthermore, the progress of agrometallomic innovativeness greatly depends on the innovative development of modern metallic analysis approaches including, but not limited to, high sensitivity, elemental coverage, and anti-interference; high-resolution isotopic analysis; solid sampling and nondestructive analysis; metal chemical species and metal forms, associated molecular clusters, and macromolecular complexes analysis; and metal-related particles or metal within the microsize and even single cell or subcellular analysis.

“…At present, GPE of Hg and Cd/Zn has been reported in ETV using gold and tungsten traps, respectively, by forming alloys. , As a successful example of ETV-GPE, Hg enrichment by gold amalgamation has been widely implemented in commercial Hg analyzers. In 2010, inspired by the success in gold amalgamation, Feng and Liu first employed a tungsten coil trap (TCT) to enrich Cd prior to AFS detection; thereafter, TCT was also employed to simultaneously trap Cd and Zn followed by ICP-MS . Thus far, however, other elements such as As have not been reported for ETV-GPE.…”

In this work, a novel integrated dielectric barrier discharge (IDBD) reactor coupled to an electrothermal vaporizer (ETV) was established for arsenic determination. It is for the first time gas-phase enrichment (GPE) was fulfilled based on the hyphenation of ETV and DBD. The mechanisms of evolution of arsenic atomic and molecular species during vaporization, transportation, trapping, and release processes were investigated via X-ray photoelectron spectroscopy (XPS) and other approaches. Tentative mechanisms were deduced as follows: the newly designed DBD atomizer (DBDA) tube upstream to the air inlet fulfills the atomization of arsenic nanoparticles in vaporized aerosol, leading to free arsenic atoms that are indispensable for forming arsenic oxides; the DBD trap (DBDT) tube traps arsenic oxides under an O 2 -domininating atmosphere and then releases arsenic atoms under H 2 -dominating atmospheres. In essence, this process is a physical−chemical process rather than an electrostatic particle deposition. Such a trap and release sequence separates matrix interference and enhances analytical sensitivity. Under the optimized conditions, the method detection limit (LOD) was 0.04 mg/kg and the relative standard deviations (RSDs) were within 6% for As standard solution and real seafood samples, indicating adequate analytical sensitivity and precision. The mean spiked recoveries for laver, kelp, and Undaria pinnatifida samples were 95−110%, and the results of the certified reference materials (CRMs) were consistent with certified values. This ETV-DBD preconcentration scheme is easy and green and has low cost for As analysis in seafood samples. DBD was proved a novel ETV transportation enhancement and preconcentration technique for arsenic, revealing its potential in rapid arsenic analysis based on direct solid sampling ETV instrumentation.

“…Due to increased levels of Zn 2+ in water systems, several analytical techniques such as atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES), inductively coupled plasma mass spectrometry (ICP‐MS), X‐ray fluorescence (XRF), and electrochemical methods have been used to monitor Zn 2+ ion levels, however these types of techniques are highly time consuming and expensive. Therefore, the development of a new method for Zn 2+ ion detection in environmental and biological systems is a critical need.…”

Phenothiazine–rhodamine‐based colorimetric and fluorogenic ‘turn‐on' sensor for Zn²⁺ and bioimaging studies in live cells

A phenothiazine-rhodamine (PTRH) fluorescent dyad was synthesized and its ability to selectively sense Zn 2+ ions in solution and in in vitro cell lines was tested using various techniques. When compared with other competing metal ions, the PTRH probe showed the high selectivity for Zn 2+ ions that was supported by electronic and emission spectral analyses. The emission band at 528 nm for the PTRH probe indicated the ring closed form of PTRH, as for Zn 2+ ion binding to PTRH, the λ em get shift to 608 nm was accompanied by a pale yellow to pink colour (under visible light) and green to pinkish red fluorescence emission (under UV light) due to ring opening of the spirolactam moiety in the PTRH ligand. Spectral overlap of the donor emission band and the absorption band of the ring opened form of the acceptor moiety contributed towards the fluorescence resonance energy transfer ON mechanism for Zn 2+ ion detection. The PTRH sensor had the lowest detection limit for Zn 2+ , found to be 2.89 × 10 −8 M. The sensor also demonstrated good sensing application with minimum toxicity for in vitro analyses using HeLa cells.
