At present, available methodologies applied in vitro focus on large groups of cells exposed to low oxygen conditions through slow-time approaches, such as environmental incubators or microfluidic devices. Here, we demonstrate a novel approach for titrating the local oxygen concentration around individual adhered PC12 cells, enabling single cells within a population to be exposed to hypoxic-like conditions. A 25 μm diameter platinum disk microelectrode performing the oxygen reduction reaction (ORR) at constant current (galvanostatic control) is used as a microscale oxygen scavenger that can be positioned precisely over individual cells. By coupling the galvanostatic oxygen challenge with confocal laser scanning microscopy (CLSM) and a commercially available hypoxia dye (Image-iT Green hypoxia reagent), we monitor the response of single cells when exposed to depleted oxygen concentrations over time. Numerical simulations are used to characterize the oxygen and pH gradient imposed by the microelectrode at different cathodic currents, revealing that within seconds, the oxygen depletion zone reaches a steady-state condition, extending a few microelectrode radii into solution, while the corresponding pH gradient is strongly compressed by the buffer solution. Cells under the microelectrode show a marked increase in average fluorescence rate relative to control, reporting their hypoxic conditions and demonstrating the effectiveness of the proposed method. Heterogenous cell response in a challenged group is also observed, highlighting the ability of this approach to investigate the natural heterogeneity in cell populations. This work provides a platform and roadmap for future studies of cellular systems where the ability to control and vary oxygen concentration on a rapid time scale would be beneficial.</p>","PeriodicalId":29800,"journal":{"name":"ACS Measurement Science Au","volume":"5 2","pages":"234–241 234–241"},"PeriodicalIF":4.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmeasuresciau.4c00100","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143832725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current methodologies for analyzing REE distributions are based on normalization of REE concentration profiles to lithological values, potentially resulting in different outcomes depending on which lithological values are used for normalization, affecting the interpretability of the data. The present work proposes an alternative approach for analyzing REE concentration profiles by applying principal component analysis (PCA) to create REE chemometric maps. The data compression allows the visualization of the REE distribution using a red-green-blue (RGB) color scale (PC1 = red channel; PC2 = green channel; PC3 = blue channel) directly on a geographical map, reflecting the chemical properties of rare-earth elements. This highlights similarities and differences in the compositional REE distribution of natural soils, facilitating the interpretability of REE data and potentially leading to new insights related to seemingly unrelated samples. Additionally, PCA applied to soil variables correlates with REE patterns and provides deeper insights into soil properties in an unsupervised manner, enhancing the interpretation of soil characteristics and implementing the ability to monitor environmental changes and study soil evolution processes. Of particular significance is the fact that applying the proposed methodology to non-normalized data yields results that are consistent with those derived from normalized data sets.

Of particular promise is nanoimprint lithography (NIL), but this can suffer from a lack of high-fidelity pattern reproducibility between master and imprinted substrates. Herein, we present a multidisciplinary investigation into gold- and iron-coated NIL sensors including custom optics and spectroscopy, scanning probe microscopy, and data analysis insights. Polyurethane NIL-made nanodome arrays were interrogated with white light transmission spectroscopy, coupled with principal component analysis (PCA) to investigate potential offsets in the photon-substrate plane interaction angle, an imperfection in NIL substrates. Large-angle mismatches (2–10°) were found to be easily discernible by PCA with statistically significant differences (<i>p</i> = 0.05). Unexpected dips in some spectra are postulated to be due to interacting localized and propagating plasmon polaritons, which is supported with a coupled two-oscillator model. General insights are made regarding the interpretation of PCA loadings, which should be related to physical phenomena, and where maximum variance is not necessarily the most meaningful criterion. Smaller angles (<1°) show no significant differences with overlapping confidence intervals in PCA space. Surface-enhanced Raman spectroscopy (SERS) measurements on gold-coated nanodomes returned relative standard deviations of 6–10% via analysis of gelatin, which is of interest as a nasal lining approximation. Interestingly, nanodomes coated in iron produced small, but useful SERS enhancements, which was subsequently interrogated via scanning thermal probe microscopy showing temperature increases of up to 5 °C over the area of one nanostructure (∼1 μm<sup>2</sup>). Nanostructures remained intact despite the surprising large local temperature increase relative to a gold-coated comparison sample (∼2 °C).
