Silanization

Definition

Silanization is a chemical process that involves the modification of surfaces using silane compounds to enhance their properties, such as hydrophobicity, biocompatibility, and adhesion. This technique is crucial in surface modification and functionalization because it allows for the introduction of specific functional groups onto materials, leading to tailored interactions with biological systems or other materials.
