Abstract
The physical and chemical properties of surfaces can be controlled by bonding nanoparticles, microspheres, or nanotextures to the surface via inorganic precursors. Surfaces can acquire a variety of desirable properties such as antireflection, antifogging, antifrosting, UV blocking, and IR absorption, while maintaining transparency to visible light. Micro or nanomaterials can also be used as etching masks to texture a surface and control its physical and chemical properties via its micro or nanotexture.

A method comprising:
- determining a first lateral dimension of each element in a structure on a surface, the structure comprising a plurality of elements, the determining based on a first physical characteristic of the structure, the first lateral dimension being in a horizontal orientation relative to the surface;
- determining a second lateral dimension of each element, the second lateral dimension being perpendicular to the first lateral dimension and in a horizontal orientation relative to the surface;
- determining a height of each element based on a second physical characteristic of the structure, the height being in a vertical orientation relative to the surface;
- determining a spacing between the elements based on the first and second physical characteristics;
- fabricating the structure comprising the plurality of elements;
- defining a plurality of patterned features on the plurality of elements, the patterned features having dimensions smaller than any of the first lateral dimension, the second lateral dimension, and the height of each element, the patterned features based on a third physical characteristic of the structure;
- functionalizing the structure with a self-saturated monolayer of a first functional group;
- functionalizing a first plurality of particles with a second functional group, the second functional group chosen so as to form a covalent or ionic bond with the first functional group;
- and
- forming a monolayer of the first plurality of particles on the structure,
- wherein the structure comprising the plurality of elements and the plurality of patterned features is monolithic.
