Abstract
Ferroptosis, as a promising therapeutic strategy for cancers, has aroused great interest. Quantifying the quick dynamic changes in key parameters during the early course of ferroptosis can provide insights for understanding the underlying mechanisms of ferroptosis and help the development of therapies targeting ferroptosis. However, in situ and quantitatively monitoring the quick responses of living cancer cells to ferroptosis at the single-cell level remains technically challenging. In this work, we selected HuH7 cells (hepatocellular carcinoma (HCC) cells) as a cell model and Erastin as a typical ferroptosis inducer. We utilized scanning electrochemical microscopy (SECM) to quantitatively and in situ monitor the early course of ferroptosis in HuH7 cells by characterizing the three key parameters of cell ferroptosis (i.e., cell membrane permeability, respiratory activity, and the redox state). The SECM results show that the membrane permeability of ferroptotic HuH7 cells continuously increased from 0 to 8.1 × 10-5 m s-1, the cellular oxygen consumption was continuously reduced by half, and H2O2 released from the cells exhibited periodic bursts during the early course of ferroptosis, indicating the gradually destroyed cell membrane structure and intensified oxidative stress. Our work realizes, for the first time, the in situ and quantitative monitoring of the cell membrane permeability, respiratory activity, and H2O2 level of the early ferroptosis process of a single living cancer cell with SECM, which can contribute to the understanding of the physiological process and underlying mechanisms of ferroptosis.

Abstract
Cadmium (Cd) is one of the most prevalent toxic metal pollutants, which is widely distributed in various environmental media and organisms. Literature studies have documented that Cd could stimulate cellular oxidative stress, and the increased intracellular reactive oxygen species (ROS) might destroy certain proteins and DNA and subsequently lead to cell apoptosis. Although several studies have studied the co-exposure between cadmium and other metals, information on the potential effects of Cd and its counterions is still lacking. In the present study, we explored the effects of nitrate and chloride on oxidative stress induced by Cd(II) at environmental exposure levels in human breast cancer cells (MCF-7) using scanning electrochemical microscopy (SECM). After incubation in CdCl2 or Cd(NO3)2, ROS production is concentration-dependent and time-dependent, and the variation trend is consistent. When MCF-7 cells were incubated at a constant Cd2+ concentration, it was found that the higher the concentration ratio of Cd(NO3)2/CdCl2, the less ROS was generated. Combined with cell-viability, intracellular acidification as well as antioxidants system tests, we observed that nitrate could be reduced to nitrite and then inhibit Cd-induced oxidative stress. Benefitting from real-time in situ imaging of cells by SECM, H2O2 was detected and quantified in a noninvasive way, and the effect of Cd at environmental exposure levels on cellular oxidative stress was explored deeper and more comprehensively. Prospectively, cytotoxicological methods based on the SECM technique would be established to explore toxic pollutant co-exposure issues at environmental exposure levels.

Abstract
Here, an Au-Cu dual-electrode tip was designed to monitor the effect of Cu2+ on the membrane permeability of a single living cell in situ using scanning electrochemical microscopy. The probe approach curves (PACs) were obtained using potassium ferricyanide as a redox mediator. Meanwhile, according to the simulation, theoretical PACs could be acquired. Thus, the cell membrane permeability coefficient (Pm) values were obtained by overlapping the experimental PACs with the theoretical values. Cu2+ was directly generated by electrolyzing the Cu electrode of the dual-electrode tip to investigate its effect on the cell membrane permeability in situ. This work has potential value to improve the understanding of the mechanism of acute heavy metal damage on the cell membrane and will also help clarify the role of heavy metal ions in physiological or pathological processes.

Abstract
Cadmium is a metallotoxin, amply encountered in the environment and derived through physical and anthropogenic activities. Its entry in various organisms leads through water and the food chain to humans, thereby inducing a plethora of pathophysiologies. Delineation of the interactive role of cadmium with physiological and physiologically relevant substrates, requires well-defined forms of cadmium arising from such interactions along with the ensuing chemical reactivity amounting to toxic manifestations and health aberrations. To implement such efforts, low molecular mass substrate metal ion binders are needed, forming species with enhanced solubility and bioavailability. To that end, α-hydroxy isobutyric acid (HIBAH2) was used in pH-specific synthetic efforts involving bulky aromatic chelators 2,2'-bipyridine (2,2'-bipy) and 1,10-phenanthroline (phen), thus leading to new crystalline materials [Cd(C4H7O3)2]n(1), [Cd(C4H7O3)2(H2O)2](2), [{Cd2(C4H7O3)2(C10H8N2)2(H2O)2}(NO3)2]n·nH2O(3), and [{Cd2(C4H7O3)2(C12H8N2)2(H2O)2}(NO3)2]n·2nH2O(4), which were physicochemically characterized (elemental analysis, FT-IR, NMR, ESI-MS, and X-ray crystallography) in the solid state and solution. Their physicochemical characteristics led to their employment in tissue-specific biological toxicity studies in three different cell lines. Their toxicity profile (cell viability, morphology, chemotacticity) was correlated through genetic biomarkers to apoptotic-necrotic processes, thereby shedding light on cadmium cellular toxicity processes. Finally, the cytoprotective action of specific chelators was examined, lending credence to the notion that appropriately structured chelators and antioxidants may be used as effective deterrent to cadmium toxicity. Collectively, structure-specificity linked to tissue-specific toxicity profiling in well-defined binary-ternary Cd(II)-HIBAH2 systems exemplifies that metal ion's aberrant interactions in the cellular milieu, meriting further probing into the development of efficient chelators in cadmium detoxification.

Abstract
Cr(III) is often regarded as a trace essential micronutrient that can be found in many dietary supplements due to its participation in blood glucose regulation. However, increased levels of exposure have been linked to adverse health effects in living organisms. Herein, scanning electrochemical microscopy (SECM) was used to detect variation in membrane permeability of single cells (T24) resulting from exposure to a trivalent Cr-salt, CrCl3. By employing electrochemical mediators, ferrocenemethanol (FcMeOH) and ferrocenecarboxylic acid (FcCOO-), initially semipermeable and impermeable, respectively, complementary information was obtained. Three-dimensional COMSOL finite element analysis simulations were successfully used to quantify the permeability coefficients of each mediator by matching experimental and simulated results. Depending on the concentration of Cr(III) administered, three regions of membrane response were detected. Following exposure to low concentrations (up to 500 μM Cr(III)), their permeability coefficients were comparable to that of control cells, 80 μm/s for FcMeOH and 0 μm/s for FcCOO-. This was confirmed for both mediators. As the incubation concentrations were increased, the ability of FcMeOH to permeate the membrane decreased to a minimum of 17 μm/s at 7500 μM Cr(III), while FcCOO- remained impermeable. At the highest examined concentrations, both mediators were found to demonstrate increased membrane permeability. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide cell viability studies were also conducted on Cr(III)-treated T24 cells to correlate the SECM findings with the toxicity effects of the metal. The viability experiments revealed a similar concentration-dependent trend to the SECM cell membrane permeability study.

Abstract
Scanning electrochemical microscopy (SECM) is a chemical microscopy technique with high spatial resolution for imaging sample topography and mapping specific chemical species in liquid environments. With the development of smaller, more sensitive ultramicroelectrodes (UMEs) and more precise computer-controlled measurements, SECM has been widely used to study biological systems over the past three decades. Recent methodological breakthroughs have popularized SECM as a tool for investigating molecular-level chemical reactions. The most common applications include monitoring and analyzing the biological processes associated with enzymatic activity and DNA, and the physiological activity of living cells and other microorganisms. The present article first introduces the basic principles of SECM, followed by an updated review of the applications of SECM in biological studies on enzymes, DNA, proteins, and living cells. Particularly, the potential of SECM for investigating bacterial and biofilm activities is discussed.

Abstract
Cadmium is a well-known metallotoxin widespread in the environment and easily reaching cellular targets in lower and higher organisms, including humans. The form(s) of that metal ion through which it interacts with biomolecular targets in a cellular milieu are critical in cell survival. Poised to investigate the structure-specific activity of Cd(II) in a cellular environment and delve into the associated biotoxic processes, binary and ternary systems of that metal ion in the presence of the physiological α-hydroxycarboxylic acid glycolic acid and aromatic (N,N')-binders 2,2'-bipyridine (2,2'-bipy) and 4,4'-bipyridine (4,4'-bipy) were examined synthetically in aqueous media and a pH-specific fashion. The arising new materials [Cd(C2H3O3)2]n (1), [Cd(C2H3O3)(C10H8N2)(NO3)]n·nH2O (2), and {[Cd(C2H3O3)(C10H8N2)(H2O)](NO3)}n·2nH2O (3) project coordination polymers, which were physicochemically characterized through elemental analysis, FT-IR, NMR, luminescence and X-ray crystallography. The distinct spectroscopic features of 1-3, with luminescence exemplifying distinct behavior (2,3), further corroborated by crystallographic analysis, lend credence to a structure-specific selection of species employed in ensuing in vitro biological studies. The emerging results in two different cell lines (3T3-L1, Saos-2) reveal a concentration-dependent, structure-specific and cell line-specific toxicity profile of Cd(II), reflecting its coordination composition and formulation, rendering it soluble and bioavailable (1,2). Mechanistic information riding on caspase-dependent investigation unravels that metal ion's specific behavior compromising cell survival and integrity. Employment of ethylenediamine tetraacetic acid (EDTA) a) shows efficient sequestration of Cd(II) away from its toxic reactivity denoting the strength of interactions involved, and b) lends credence to further development of appropriately configured organic binders, selectively providing molecular protection from Cd(II) toxicity.
