Paper Abstract

Quantification of ligand-receptor engagement in human breast cancer cells and tumor xenografts has been performed using fluorescence lifetime Forster resonance energy transfer (FLI-FRET) imaging at multiscale, from in vitro microscopy to in vivo macroscopy and across visible to near-infrared wavelengths. We have developed a 3D convolutional neural network architecture, named FLI-Network (FLI-Net), to process fluorescence lifetime decays acquired by either Time-Correlated Single-Photon Counting (TCSCP)- or gated ICCD- based instruments. FLI-FRET ability to measure target engagement across different imaging platforms as well as post-processing analysis approaches can find numerous applications in pre-clinical drug delivery and targeted therapy assessment and optimization.
