In analytical chemistry, the application of ILs to chemical separation and solvent extraction has been investigated. However, there have been a smaller number of reports on the mechanisms of chemical equilibria in the solvents of ILs at a molecular level. In this review, the series of our investigations on the complex formation of Ni<sup>2+</sup> ion with molecular liquids (MLs) in imidazolium-based ILs, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([C<sub>2</sub>mim][TFSA]) and 1-methyl-3-octylimidazolium bis(trifluoromethylsulfonyl)amide ([C<sub>8</sub>mim][TFSA]) was summarized. The MLs involved methanol (MeOH), ethanol (EtOH), acetonitrile (AN), and dimethyl sulfoxide (DMSO). In [C<sub>2</sub>mim][TFSA], the Ni<sup>2+</sup>-ML complexes are stabler in the sequence of DMSO >> AN > EtOH ≈ MeOH complexes, which almost depends on the electron donicities of MLs. In contrast, in [C<sub>8</sub>mim][TFSA], the sequence changes to AN > DMSO > EtOH > MeOH complexes, despite of the lowest electron donicity of AN. Thus, only the electron donicities of MLs do not decide the stability of the complexes. The reasons for the stabilities of the Ni<sup>2+</sup>-ML complexes were interpreted in terms of the microscopic interactions between ML and the ILs’ cation observed by the infrared (IR) and <sup>1</sup>H and <sup>13</sup>C nuclear magnetic resonance (NMR) spectroscopic techniques. Furthermore, to clarify the effects of ML cluster formation on the complex formation mechanisms, the heterogeneous mixing between IL and ML were quantitatively evaluated by small-angle neutron scattering (SANS) at the mesoscopic scale.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":"41 5","pages":"609 - 622"},"PeriodicalIF":1.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143630062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This functionality can be further enhanced by integrating metal complexes non-covalently with various media, such as materials or separation platforms. Over the past four decades, the author has explored metal complex systems, including thiacalixarene–lanthanide(III) complexes, diradical platinum(II) complexes, and MOF-74, which exhibit a broad spectrum of functionalities spanning analytical applications to theranostics. Examples discussed in this review include luminescent supramolecular sensors for soft-metal ions, upconverting complexes, near-infrared light-absorbing probes for pH and hydrophobic cavities, magnetic resonance imaging (MRI), photoacoustic imaging, photothermal therapy, and neutron capture therapy. The multifunctionality of these systems arises from their cooperative, synergistic, and supramolecular nature, underpinned by non-covalent interactions among their components.

An important alteration in cancer progression is a significant increase in sialic acid (SA) levels, making sialic acid one of an interesting biomarker for cancer type diversity. Here, novel SERS nano-biosensors were fabricated employing molecularly imprinted polymers (MIPs) particles loaded with Ag nanoparticles (AgNPs) to form high affinity toward sialic acid on CTCs. In this work, the glycol-specific MIPs are produced using precipitation polymerization. The nanocomposite was characterized by Fourier transform infrared spectroscopy (FTIR), zeta potential, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Consequently, CTC can be rapidly detected in mouse blood in a specific and sensitive manner, as low as 1 cells/ml. In addition, a good linear relationship was observed between CTC concentration and signal intensity (<i>R</i><sup>2</sup> = 0.9881). Moreover, the SERS nano-biosensors was used to detect CTC with excellent precision (relative standard deviation, RSD = 3.9%) and good repeatability (RSD = 6.8%). Therefore, this inexpensive, highly sensitive, and rapid method using SERS nano-biosensors can quickly detect CTCs and may prove to be a new platform to be an early diagnostic tool for cancer patient detection.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7802,"journal":{"name":"Analytical Sciences","volume":"41 4","pages":"447 - 455"},"PeriodicalIF":1.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ECL efficiency of TADF molecules is increased by spin up-conversion from the T<sub>1</sub> to S<sub>1</sub> state, and that of PPABs is incremented kinetically due to the slower rate for the T<sub>1</sub> state formation than the S<sub>1</sub> state formation. The excimer formation mechanism of Py and its derivative in ECL is discussed. It is shown that very sharp ECL spectra can be obtained from Eu(III) and Tb(III) complexes.

Encoding spectral information directly as color coordinates within digital images enables rapid data acquisition. In addition, simple instrumentation that requires only a camera as a detector expands the versatility of solving tasks that occur in microspectroscopy.

Normally, the IL-6 degree keeps a low content (< 40.0 pg mL<sup>−1</sup>) in bodies, but when its degree becomes higher, several serious conditions (e.g., urocystitis and infections) may occur. Hence, it is very essential to design a highly effective technology for monitoring IL-6 as a biomarker. In the present work, through adopting carbon black (CB) as substrate substance, o-diaminobenzene as electropolymerized monomer and [Fe(CN)<sub>6</sub>]<sup>4−/3−</sup> as the signal probe, a low-cost, sensitive and simple molecularly imprinted polymer (MIP) electrochemical sensing platform was designed to detect the IL-6 degree. The experiments revealed that the current of [Fe(CN)<sub>6</sub>]<sup>4−/3−</sup> probe at the MIP sensor would decrease along with the increase of IL-6 degree. Owing to the prominent properties of CB (e.g., high conductivity and surface area as well as stability) and high target-recognition capability of MIP, the as-proposed MIP sensor offers wide linearity (0.1–800 pg mL<sup>−1</sup>) and low analytical limit (0.03 pg mL<sup>−1</sup>); meanwhile, it possesses good repeatability, stability, and practical applications.
