The synergy between AI and nanotechnology holds immense promise for driving the discovery of next-generation nanomaterials across multiple industries, shaping a more sustainable and innovative future.

Introduction

Nanomaterials, characterized by their dimensions in the nanoscale (1-100 nm), exhibit enhanced properties due to quantum effects, high surface area-to-volume ratio, and unique atomic arrangements. These attributes have made nanomaterials

essential across various industries, enhancing electrical, optical, and mechanical performance. Their applications span drug delivery systems, diagnostics, tissue engineering [1], energy storage solutions like batteries and supercapacitors, and sustainable energy technologies, including solar cells and fuel cells [2]. In environmental sustainability, nanotechnology addresses critical challenges, such as water purification, where materials like titanium dioxide play a vital role in photocatalysis, and graphene revolutionizes membrane technology for desalination. Similarly, nanoelectronics, a specialized branch of nanotechnology, has been pivotal in miniaturizing electronic components, enabling advancements in compact and efficient devices [3].

The rapid integration of Artificial Intelligence (AI) into nanotechnology has further transformed the field. AI excels in processing massive and complex datasets, enabling breakthroughs in predictive modeling, optimization, and materials discovery. While AI has revolutionized domains like biology, chemistry, and materials science, its specific integration into nanotechnology is particularly impactful. AI-driven Machine Learning (ML) models have significantly improved property predictions, optimized synthesis conditions, and accelerated the discovery of new materials [4]. Such advancements address the limitations of traditional material design approaches, which are often manual, slow, and costly. In nanomaterials research, AI enhances High-Throughput Experimentation (HTE) by efficiently analyzing intricate datasets from simulations or experiments, reducing the time required to identify materials with desired functionalities [5]. AI-based computational models also predict material behavior under specific conditions, minimizing costs associated with trial-and-error processes. These innovations enable the discovery of functional nanomaterials tailored for particular applications in healthcare, electronics, and energy [6]. By focusing on unique benefits, such as the functionalization of nanomaterials for optimized biological, electronic, and energy applications, AI-driven research promises to redefine the future of nanotechnology. This convergence of AI and nanotechnology accelerates discovery and addresses pressing challenges in sustainability and innovation [7].

Nanomaterials and their Applications

Nanomaterials are materials that have been engineered to be extremely small at the scale of nanometers and, therefore, possess new functional properties vastly superior to bulk materials due to quantum effects and very high surface-area-to-volume ratios. This demonstration of properties such as increased strength, conductivity, and reactivity has made them very useful in many contexts [8].

There are several types of nanomaterials, which include:

• Nanoparticles: Spherical particles, commonly metal (gold, silver), oxides (zinc oxide, titanium dioxide), or polymers, have applications in catalysis, biomedicine, and energy storage [9].
• Nanocomposites: Hybrid materials with nanoparticles within a matrix improve their mechanical, thermal, or electrical properties. Nanocomposite materials are used in a broad range of applications, such as in the automobile, aerospace, and building industries [10].
• 2D Materials: Thin sheets of materials such as graphene, molybdenum disulfide (MoS2), and hexagonal boron nitride display unique electronic, optical, and sensing properties [11].

Nanoparticles also have potential applications in nanoscale technology, including components of quantum dots and other nanostructures. They exhibit different properties from the bulk material, which are generally expected to alter depending upon a specific size, such as Nanowires and nanotubes (such as carbon nanotubes). Nanorods (Dimensional structures) have beneficial properties like mechanical strength and high electrical conductivity, increased surface area for catalyzing reactions, and sensors, which make them attractive for use in certain application types like flexible electronics, energy storage, and drug delivery.

2. Electronics: One industry that is gaining significant dividends in yield enhancers through the use of nanomaterials is the electronics industry, with carbon nanotubes and graphene being only a pair among many others.

For instance, transistors based on carbon nanotubes are predicted to outperform silicon-based transistors in speed and energy efficiency, whereas the application of graphene into flexible electronics leads to abundant possibilities [13].
