Area of Science:

Biomedical Engineering
Nanotechnology
Cancer Diagnostics

Background:

Pancreatic cancer has a high mortality rate, emphasizing the need for early detection methods.
Current screening tools lack the high-throughput capability for large-scale application.
A gap exists in rapid, efficient methods for analyzing biomarkers from exosomes.

Purpose of the Study:

To develop a high-throughput platform for simultaneous exosome and metabolic profile extraction.
To identify novel biomarkers for early pancreatic cancer diagnosis, risk stratification, and staging.
To address challenges in large-scale testing and confounding factors in big data analysis.

Main Methods:

Development of a high-throughput On-Target Array Extraction Platform (OTAEP) using sintered metal-organic frameworks (MOFs).
Utilized geometry-dependent photothermal conversion efficiency to identify optimal MOF functional units.
Applied Surrogate Variable Analysis to metabolic profiles for eliminating confounding factors.
Validated identified biomarkers using MS/MS experiments.

Main Results:

OTAEP achieved exosome enrichment in 10 minutes and metabolic fingerprint extraction in under 1 second, with over five reuses.
Identified five novel biomarkers with high diagnostic accuracy (94.1% sensitivity, 98.8% specificity, 94.9% precision).
Demonstrated simultaneous early diagnosis, risk stratification, and staging of pancreatic cancer.

Conclusions:

The developed OTAEP overcomes throughput limitations for large-scale pancreatic cancer screening.
The identified biomarkers and analytical approach significantly enhance the accuracy of early cancer detection.
This breakthrough offers a promising solution for improving pancreatic cancer survival rates through advanced diagnostics.
