Advanced Nanomaterials

Advanced nanomaterials refer to nanoscale materials that exhibit unique properties and functionalities due to their small size and high surface area-to-volume ratio. These materials are engineered at the nanoscale to achieve specific properties for various applications. Nanomaterials often exhibit superior mechanical properties such as strength, hardness, and flexibility compared to their bulk counterparts. Some nanomaterials, like carbon nanotubes and graphene, exhibit excellent electrical conductivity, making them suitable for use in electronics and energy storage devices. The high surface area-to-volume ratio of nanomaterials results in increased chemical reactivity, enabling applications in catalysis and sensors. Nanomaterials can exhibit unique optical properties, including enhanced light absorption and emission, which are useful in imaging, sensing, and display technologies. Many nanomaterials are biocompatible and can be used in biomedical applications such as drug delivery, imaging, and tissue engineering. Nanomaterials are used in batteries, super capacitors, and fuel cells to improve energy storage and conversion efficiency. There are concerns about the potential toxicity of some nanomaterials, which requires careful evaluation and regulation. Scaling up the production of nanomaterials while maintaining their desired properties can be challenging.
