Опубликована: Янв. 23, 2025

Abstract Biorecognition elements immobilized into nanopores have transformed point‐of‐care (POC) diagnostics by converting molecular interactions electrical and fluorescent signals.This study introduces Bio‐Sensei, a high‐throughput screening (HTS) microfluidic platform based on nanopore biosensing. Integrating robotic sampler, electrochemical, fluorescence setup, Bio‐Sensei operates as an Internet of Things (IoT) with integrated data analysis. The platform's utility is demonstrated functionalized amino terminal Cu(II)‐ Ni(II)‐binding (ATCUN) peptide ion track‐etched membrane. Automated testing atchieves significantly higher F‐stat value than the critical treshold, while unsupervised clustering reveals optimalnanopores pore size. biosensordemonstrates remarkable stability, selectivity, sensitivity detection limits 10 −6 using −15 Musing cyclic voltammetry measurements. Combining these methods enhances machine learning models for Cu 2+ concentration prediction, achieving receiver operating characteristic area under curve values exceeding 95%.
