Selective Detection of Mixtures via a Single Nonselective Sensor—Making the Unworkable Sensor Workable by Machine Learning

Abstract: Highly selective and sensitive detection of chemical mixtures by a single sensor consistently suffers from overlapping response signals. Previous researchers have to make a detour to avoid overlapping through preparing selective sensor materials, tedious preseparation, and time‐consuming operation. Nowadays, machine learning (ML), as one remarkable branch of artificial intelligence (AI), possesses advantages to modernize pathways to approach chemical challenges and provides a novel short cut for chemical mixtu… Show more

“…The solution described in this work can be categorized as the next step in the field of Computational chemistry Machine learning assisted (CompChem + ML), in which the ML would be directly installed into the electrochemical readout system itself. [ 18 ] Furthermore, ML‐based methods have been demonstrated capable of quantitative detection of chemistry mixtures via a single nonselective sensor, [ 19 ] metabolites, [ 20 ] and other biomolecules. [ 21 ]…”

“…The luminescence of CTL reaction was collected and converted into digital signals by a photomultiplier tube (PMT), purchased from Hamamatsu Photonics Co., Ltd. It is worth mentioning that the previous study [46] has proved that the air flow inside the CTL sensor is laminar and can be simplified into a 2D model. The CTL sensor chamber is composed of a ϕ20 × 50 mm quartz tube which is represented in the simulation model as a 40 × 30 mm rectangle.…”

“…Previous researchers delved into sensing mechanisms of various gases in search of distinctive signal features. [46][47][48] This section demonstrates how adopting the multiple overlapping sniffs (MOSS) strategy provides more differentiated sensing signals, effectively enhancing VOC recognition. In this experiment, only sensor No.1 is applied to recognize three kinds of standard VOC gases, that is, butane, ethylene and acetylene (C 4 H 10 , C 2 H 4 , and C 2 H 2 ).…”
