Abstract
We present an electrochemical impedance spectroscopy (EIS) technique that can detect and characterize single particles as they collide with an electrode in solution. This extension of single-particle electrochemistry offers more information than typical amperometric single-entity measurements, as EIS can isolate concurrent capacitive, resistive, and diffusional processes on the basis of their time scales. Using a simple model system, we show that time-resolved EIS can detect individual polystyrene particles that stochastically collide with an electrode. Discrete changes are observed in various equivalent circuit elements, corresponding to the physical properties of the single particles. The advantages of EIS are leveraged to separate kinetic and diffusional processes, enabling enhanced precision in measurements of the size of the particles. In a broader context, the frequency analysis and single-object resolution afforded by this technique can provide valuable insights into single pseudocapacitive microparticles, electrocatalysts, and other energy-relevant materials.

Abstract
While single nanoparticle electrochemistry holds great promise for establishing the structure-activity relationship (SAR) of electroactive nanomaterials, as it removes the heterogeneity among individuals, successful SAR studies remain rare. When one nanoparticle is seen to exhibit better performance than the others, it is often simply attributed to better activity of the particular individual. By taking the ion insertion reaction of Prussian blue nanoparticles as an example, here we show that the electrical contact between nanoparticles and electrode, a previously overlooked factor, was greatly distinct from one nanoparticle to another and significantly contributed to the apparent heterogeneity in the reactivity and cyclability. An individual nanoparticle with intrinsically perfect structure (size, facet, crystallinity, and so on) could be completely inactive, simply due to poor electrical contacts, which blurred the SAR and likely caused failures. We further proposed a sputter-coating method to enhance the electrical contacts by depositing an ultrathin platinum layer onto the sample. Such an approach was routinely adopted in scanning electron microscopy to improve the electron mobility between nanoparticles and substrate. Elimination of heterogeneous contacts ensured that the electrochemical activity of single nanoparticles can be accessed and further correlated with their structural features, thus paving the way for single nanoparticle electrochemistry to deliver on its promises in SAR.

Abstract
We report an electrochemical sensor for the detection of lithium ions (Li+) in authentic human saliva at lithium manganese oxide (LiMn2O4)-modified glassy carbon electrodes (LMO-GCEs) and screen-printed electrodes (LMO-SPEs). The sensing strategy is based on an initial galvanostatic delithiation of LMO followed by linear stripping voltammetry (LSV) to detect the reinsertion of Li+ in the analyte. The process was investigated using powder X-ray diffraction and voltammetry. LSV measurements reveal a measurable lower limit of 50.0 μM in both LiClO4 aqueous solutions and synthetic saliva samples, demonstrating the applicability of the proposed analytical method down to low Li+ concentrations. Four different samples of authentic human saliva were then analyzed with the established sensing strategy using LMO-SPEs, showing good linearity over a concentration range up to 5.0 mM Li+ with high reproducibility (RSD < 7%) and applicability for routine monitoring purposes. The total time needed to analyze a sample is less than 3 min.
