Background:

Designing nano-engineered particles for targeted therapeutic and diagnostic agent delivery presents significant challenges.
Understanding particle-cell interactions, influenced by physicochemical properties, is crucial for rational design.
Mathematical and computational methods can isolate particle-cell interaction details from complex biological systems.

Purpose of the Study:

To develop an interpretable machine learning framework for elucidating particle-cell interactions from experimental data.
To integrate data-driven modeling with existing biological knowledge for enhanced predictive power.
To provide a tool for quantitative evaluation of nano-engineered particle design choices.

Main Methods:

A novel machine learning framework was developed to analyze particle-cell interaction data.
The framework utilizes a data-driven approach augmented with biological knowledge.
Applied to association data from 30 diverse particle-cell pairs, including various cell lines and particle types (polymers, sizes, surface functionalizations).

Main Results:

The machine learning framework successfully elucidated particle-cell interactions, producing interpretable models.
Remarkably consistent models were learned across diverse experimental conditions, with only four unique interaction models identified out of 2048 possibilities.
Nonlinear saturation effects were identified as a key factor governing particle-cell interactions.

Conclusions:

The developed machine learning framework offers an interpretable approach to understanding nano-engineered particle-cell interactions.
The findings highlight the critical role of nonlinear saturation effects in particle-cell interactions.
This framework facilitates robust estimation of particle performance, aiding in the rational design of effective delivery systems.
