Biophotonic Nanoparticle-enabled Laser Blood Test for Early Detection of Pancreatic Cancer

Introduction

Pancreatic ductal adenocarcinoma (PDAC) is a deadly form of cancer that is on the rise due to various factors, including an aging population and unhealthy lifestyles. Regrettably, PDAC is among the top cancer killers, with a dismal five-year survival rate of less than 10%. The lack of adequate screening programs is a significant factor contributing to this dire statistic.

Early Detection Potential

However, the identification of PDAC in its early stages could help reduce the mortality rate by as much as 80%. The project LASERBLOOD (Biophotonic Nanoparticle-enabled Laser Blood Test for Early Detection of Pancreatic Cancer) aims to develop an in vitro diagnostic test based on the fluorescence lifetime fingerprint of the personalized protein corona, offering critical information at every stage of PDAC progression.

Protein Corona

The protein corona (PC) is a coating of bio-molecular substances surrounding nanoparticles when exposed to biofluids. It is both personalized and disease-specific, making it an ideal marker to monitor the variation of nanoparticle PC and correlate it to the development of PDAC.

Methodology

The analysis will use fluorescence lifetime (FL) analysis, a non-invasive, reactant-free, and real-time technique.

Phase One: Mouse Model

In the initial phase, the consortium will utilize a mouse model (MKC) to identify the FL fingerprint of protein corona at each stage of PDAC development. The MKC mouse model is genetically engineered to be bioluminescent and develop PDAC in a controlled manner.

Linking Imaging and Analysis

By linking the development of PDAC observed through bioluminescent imaging to the FL response of PC in blood samples, the consortium will provide an unprecedented fingerprint of the disease's progression from its first occurrence.

Phase Two: Human Validation

At a second stage, the project will validate on humans the use of the FL fingerprint of protein corona as a tool for the early diagnosis of PDAC. The findings will provide the scientific and technological foundation for the development of an in vitro PDAC test for large-scale screening of the population.
