Aug 4, 2026

The rapid growth of engineered nanoparticles in industry and medicine raises urgent concerns about toxicity arising from complex, difficult-to-forecast interactions with biological systems. A central challenge is accurately predicting nanoparticle toxicity as it depends on interacting physicochemical factors such as size, shape, surface charge, chemical composition, and oxygen content. This study applies machine learning models—Decision Trees, Random Forests, and XGBoost—to learn toxicity patterns from physicochemical properties. Results indicate oxygen presence strongly affects toxicity while particle size, surface area, dosage, and exposure time remain critical. By integrating computational chemistry with machine learning, the work supports safer nanomaterial design.

Iqra yousaf Mphill Applied Chemistry University of Engineering and Technology Lahore Title: AI and Machine Learning Approches for Predicting Nanoparticles Toxicity The Critical Role of Physiochemical Properties Abstract:The rapid proliferation of nanoparticles in various industries has raised significant concerns about their potential toxicity, primarily due to the complex and unpredictable ways these materials interact with biological systems. One of the primary challenges in this field is accurately predicting the toxicity of nanoparticles, which is influenced by a multitude of factors including their size, shape, surface charge, chemical composition, and the presence of oxygen atoms.To address this challenge, this study employs machine learning models to predict nanoparticle toxicity based on their physicochemical properties. The models used in this research include Decision Trees, Random Forests, and XGBoost. These machine learning approaches were selected for their ability to efficiently process large datasets and uncover intricate patterns within the data that are not immediately apparent through traditional methods.The analysis revealed that while the presence of oxygen atoms significantly influences toxicity, other properties such as particle size, surface area, dosage, and exposure time are also critical factors. The machine learning models consistently highlighted these factors as key determinants of toxicity, demonstrating that a multifactorial approach is essential for accurate predictions.The importance of computational chemistry in this context cannot be overstated. It provides the necessary tools to simulate and predict the behavior of nanoparticles in biological environments, thereby reducing the need for time-consuming and costly experimental procedures. Through the integration of computational methods and machine learning models, this study advances our understanding of nanoparticle toxicity and contributes to the development of safer nanomaterials. Key words: Nanoparticles, Toxicity, Machine Learning, Physicochemical Properties, Decision Trees, Random Forests, XGBoost, Computational Chemistry Introduction: Over the past few decades, nanotechnology has seen rapid advancements, leading to a significant increase in the variety of engineered nanoparticles employed across various industries, technologies, and medical fields. These nanoparticles offer substantial benefits due to their unique physicochemical properties, which arise from their nanoscale size. However, this same small size also results in behaviors that differ significantly from their bulk material counterparts, making it challenging to predict their potential health and environmental impacts. Consequently, a recent focus in nanotechnology research has been on exploring how nanomaterials interact with biological systems [ 1] . There is growing concern about the potential toxicity of nanomaterials and how they might affect biological systems. The forthcoming era may well be labeled the "Nano Era" due to its profound impact on various aspects of society, particularly in product design and manufacturing. This approach extends the lifespan of industrial products by improving their qualities, features, and appearance. Therefore, it is crucial for industrial designers to educate the public on the significance and elegance of technology, and how to adapt it to better serve humanity. An industrial designer's true success lies in their ability to understand consumer needs and leverage technology to create products that are both functional and visually appealing [2, 3] . Nanotechnology is defined as the research and development of technology at the atomic, molecular, or macromolecular scales, typically within the range of about 1 to 100 nanometers [4] . When comparing modern medical practices to those of the past century, it is impossible not to recognize the countless advancements that have been made to treat diseases that were once considered
