In nanotechnology, the surface properties of materials can significantly impact their functionality and integration into systems. The contact angle helps researchers understand how nanomaterials interact with other substances, which is crucial for applications like developing hydrophobic and hydrophilic surfaces, drug delivery systems, and nanocoatings. For instance, a low contact angle indicates that the material is hydrophilic and can bond well with water, which is often desired in biomedical applications. Conversely, a high contact angle suggests hydrophobicity, useful in creating self-cleaning surfaces.
