Material Degradation One of the primary reasons for reduced efficiency is the degradation of nanomaterials. Over time, exposure to environmental conditions such as moisture, temperature changes, and chemical interactions can deteriorate the properties of materials like carbon nanotubes, quantum dots, and nanoparticles. This can lead to a decline in their performance.
Agglomeration Nanoparticles tend to agglomerate due to their high surface energy. This [agglomeration](https://) can result in the loss of the unique properties that individual nanoparticles exhibit, thereby reducing the efficiency of the nanomaterials in applications such as drug delivery and catalysis.
Fabrication Challenges The process of fabricating nanomaterials and devices at a consistent quality is fraught with challenges. Variations in the synthesis process can lead to inconsistencies in size, shape, and surface properties, which can, in turn, affect the performance of the nanomaterials.
