Clear-Box Machine Learning for Virtual Screening of Two-Dimensional Nanozymes to Target Tumor Hydrogen Peroxide.

Targeting tumor hydrogen peroxide (H 2 O 2 ) with catalytic materials has provided a novel chemotherapy strategy of solid tumors. Because numerous materials have been fabricated so far, there is an urgent need for an efficient in-silico method, which can automatically screen out appropriate candidates from materials libraries for further therapeutic evaluation. In this work, adsorption-energy-based descriptors and criteria are developed for the catalase-like activities of materials surfaces. The result enables a comprehensive prediction of H 2 O 2 -targeted catalytic activities of materials by density functional theory (DFT) calculations. To expedite the prediction, machine learning models, which efficiently calculate the adsorption energies for two-dimensional materials without DFT, are further developed. The finally obtained method takes advantage of both interpretability of physics model and high efficiency of machine learning. It provides an efficient approach for in-silico screening of two-dimensional materials toward tumor catalytic therapy, and it will greatly promote the development of catalytic nanomaterials for medical applications.
