Overview

Diagnostic study demonstrates 90.91% accuracy for early gastric cancer detection using an optical microbubble biosensor, highlighting the potential of machine-learning-assisted vesicle analysis.

Key Points

To develop an ultrasensitive, label-free microfluidic biosensor coupled with machine learning for the rapid detection of extracellular vesicles and early-stage gastric cancer discrimination.
Fabricated a label-free microfluidic microsensor using an ultrahigh-Q whispering-gallery-mode microbubble resonator to detect extracellular vesicles in complex fluid environments.
Integrated an interpretable machine learning algorithm to extract and analyze complex optical spectral features from extracellular vesicles.
Conducted clinical validation to evaluate discrimination accuracy between patients with early-stage gastric cancer and healthy controls against conventional plasma tumor biomarkers.
Achieved an estimated limit of detection of 23.87 extracellular vesicles per milliliter (EVs/mL) using the optical microbubble resonator.
Attained a clinical discrimination accuracy of 90.91% for differentiating early-stage gastric cancer from healthy controls, significantly exceeding the performance of standard tumor biomarkers.
