Nanomaterials vs. Nanoparticles — What's the Difference?
By Fiza Rafique & Urooj Arif — Published on April 24, 2024
Nanomaterials are materials with any external dimension in the nanoscale or having internal structure or surface structure in the nanoscale, while nanoparticles are particles between 1 and 100 nanometers in size.

Key Differences
Nanomaterials encompass a broad category of materials that include nanoparticles but also extend to nanostructured materials like nanotubes, nanofibers, and nanocomposites. These materials can have unique physical, chemical, and biological properties different from their bulk counterparts due to their small size and high surface area to volume ratio. Nanoparticles, on the other hand, specifically refer to ultrafine particles with dimensions between 1 and 100 nanometers. Due to their size, nanoparticles exhibit unique properties that are not found in the same materials at a larger scale, such as increased reactivity and altered electrical or optical behaviors.
Nanomaterials are utilized across various fields, from medicine and electronics to energy storage and environmental applications, leveraging their enhanced reactivity, strength, electrical characteristics, and other novel properties. While nanoparticles can be made of metals, ceramics, polymers, or carbon-based materials and are used in applications like drug delivery systems in medicine, catalysts in chemical reactions, and pigments in paints and coatings.
The distinction between nanomaterials and nanoparticles lies in their scope and application. While nanoparticles are a subset of nanomaterials, characterized by their specific size range, nanomaterials include a wider variety of nano-sized structures and composites, each with its unique set of properties and uses.
Nanoparticles are primarily defined by their size, which imparts them with a high surface area to volume ratio, leading to unique optical, magnetic, and electrical properties. Nanomaterials, including those that are not nanoparticles, such as nanofibers or nanosheets, exploit the benefits of the nanoscale in different ways.
The key difference between nanomaterials and nanoparticles lies in their definition and range of applications. Nanomaterials refer to a broad category that encompasses various nano-sized structures and composites, including nanoparticles, which are specifically sized particles that exhibit unique properties due to their small dimensions. Both play crucial roles in advancing technology and offering solutions across a wide range of industries.
