TransMA, a multi-modal deep learning model, predicts ionizable lipid nanoparticle transfection efficiency by integrating 3D geometric and 1D sequential molecular features. The model achieves superior prediction accuracy and offers atomic-level interpretability, particularly in identifying key atoms responsible for large changes in efficiency.
Key insights
- The fusion of diverse molecular structural features (3D geometric and 1D sequential) is essential for achieving state-of-the-art accuracy in predicting LNP transfection efficiency.
- Atomic-level interpretability, provided by mechanisms like mol-attention, can pinpoint critical substructures influencing LNP performance, facilitating rational design.
- Focusing on 'transfection cliffs' helps the model learn nuanced structure-property relationships, crucial for designing robust LNP systems.
