Summary
This study presents a novel bioelectronic sensor using locusts to detect lung cancer biomarkers. The platform achieves high accuracy in identifying volatile organic compounds and classifying lung cancer cell lines for early diagnosis.
Area of Science:
- Bioelectronics
- Neuroscience
- Biomarker Detection
Background:
- Current lung cancer screening methods face limitations in accessibility, sensitivity, and cost.
- Early detection of lung cancer is crucial for improving treatment outcomes.
- Volatile organic compounds (VOCs) are promising biomarkers for non-invasive cancer detection.
Purpose of the Study:
- To develop a novel bioelectronic sensing platform for non-invasive lung cancer biomarker detection.
- To integrate the locust olfactory system with a flexible microelectrode array (MEA) for enhanced sensitivity and robustness.
- To evaluate the platform's capability in detecting and classifying lung cancer-related VOCs and cell lines.
Main Methods:
- Fabrication of flexible, dual-sided microelectrode arrays (MEAs) using a folding-annealing technique and PEDOT:PSS functionalization.
- Utilizing the locust olfactory system for detecting VOCs from lung cancer cell lines.
- Recording and analyzing neural activity in the locust antennal lobe using advanced dimensionality reduction and population neuronal response analysis.
Main Results:
- The developed MEAs demonstrated high electrode density and low impedance, with mechanical flexibility and stability.
- The platform successfully detected lung cancer-related VOCs at low concentrations (1 ppm) and classified unknown VOCs with 100% accuracy.
- Individual VOC biomarkers were detected and classified with 86% accuracy, and lung cancer cell lines (NSCLC and SCLC) were classified with 85% accuracy.
Conclusions:
- The bioelectronic sensing platform offers a novel, non-invasive, and efficient approach for early lung cancer diagnosis.
- Integration of biological sensory systems with bioelectronics provides a promising avenue for enhancing clinical diagnostics.
- The platform's high accuracy in detecting VOCs and classifying cell lines supports its potential as an accessible cancer screening tool.
