Abstract Single‐cell mass spectrometry (MS) is significant in biochemical analysis and holds great potential biomedical applications. Efficient sample preparation like sorting (i.e., separating target cells from the mixed population) desalting moving off non‐volatile salt solution) urgently required single‐cell MS. However, traditional methods suffer complicated operation with various apparatus, or insufficient performance. Herein, a one‐step strategy by leveraging label‐free impedance flow cytometry (IFC) based microfluidics proposed. Specifically, IFC framework to characterize sort single‐cells adopted. Simultaneously sorting, cell transferred local high‐salinity buffer MS‐compatible solution. In this way, are achieved collected can be directly fed for MS analysis. A high efficiency (>99%), cancer purity (≈87%), whole workflow of impedance‐based separation normal (MCF‐10A) (MDA‐MB‐468) verified. As standalone module, microfluidic chip compatible variety methods, envisioned provide new paradigm efficient preparation, further multi‐modal electrical metabolic) characterization single‐cells.

Deformability is an essential feature of red blood cells (RBCs), enabling them to undergo significant shape change in response external forces. Impaired erythrocyte deformability associated with several pathologic conditions, and quantitative measurement RBC critical understanding diagnosing related diseases. Whereas traditional approaches cell mechanical characterization generally have limited throughput, emerging microscale technologies are opening new opportunities for high-throughput cytometry at the single-cell level.In this work, we propose innovative microfluidic system based on (i) a hyperbolic microchannel induce deformation by extensional flow, (ii) electrical sensing zone coplanar electrodes evaluate deformed shape.RBC under flow achieved, quantified means anisotropy index, throughput 300 cell/s. Measurements healthy chemically stiffened RBCs demonstrate that index can be used characterize deformability, as alternative indices high-speed image processing.A contactless optics-free approach analysis has been presented.Due its simplicity potential integration, proposed holds promises fast low-cost assays, especially point-of-care resource-limited settings.

However, accurate differentiation of different species bacteria by IFC technology remains a challenge owing insignificant differences data. Here, we developed convolutional neural networks (ConvNet) deep learning approach enhance accuracy and efficiency toward distinguishing various bacteria. First, more than 1 million sets impedance data (comprising 42 characteristic features each set) groups were trained ConvNet model. To improve analysis, Spearman correlation coefficient mean decrease random forest algorithm introduced eliminate feature interaction extract opacity related wall membrane structure as predominant differentiation. Moreover, 25 optimized selected with accuracies >96% three (bacilli, cocci, vibrio) >95% two bacilli (Escherichia coli Salmonella enteritidis), compared machine algorithms (complex tree, linear discriminant, K-nearest neighbor algorithms) maximum 76.4%. Furthermore, was achieved on spiked samples mixing ratios.
