Abstract: Disclosed herein are chemically configurable diamonds tailored for self-cleaning, dirt repelling, and anti-smudge technology for sensing, optical, and ornamental applications. This document describes an invention for generating chemically configurable diamonds. Applications include anti-smudge, self-cleaning, color alteration, and debris resistance for diamond for jewelry or other ornamentation, optical, quantum computing, for chemical functionalization for sensors or electronic devices that rely on chemical interactions with diamonds or defects therein. Diamond surfaces are chemically inert and therefore require chemical modification to attach secondary coatings. Secondary coatings can be varied depending on application demands. Chemical reactions are employed to modify the surface wetting properties of the diamond.

Abstract: Disclosed herein are coated gemstones, coatings for gemstones, methods of coating gemstones, and methods of using coatings on gemstones to avoid blemishes on gemstones. In some embodiments, diamonds are functionalized with anchor molecules that bind hydrophilic cyclodextrin molecules to confer hydrophilicity on the diamond. In some embodiments, the diamonds resist dirt and grime build-up.

Abstract: Disclosed herein are molecularly coated surfaces, methods of coating surfaces, and methods of using coatings on surfaces. In some embodiments, the coated surfaces are useful in applications to avoid blemishes on gemstones, confer antimicrobial activity on a surface, confer a therapeutic property to a surface, detect an analyte, change the color of a surface, and or to change the physical and/or chemical properties of a surface.

Abstract: Described are metal organochalcognides which are bulk nanomaterials, expressing monolayer properties in their as-synthesized states. Also described are certain novel metal organochalcogenide compositions. Further described are several methods of preparation of metal organochaleogenides, both solution- and vapor deposition-based, and methods of use of the resulting metal chalcogenides in assays and devices.

Abstract: Methods and assemblies for the construction of liquid-phase alloy nanoparticles are presented. Particle formation is directed by molecular self-assembly and assisted by sonication. In some embodiments, eutectic gallium-indium (EGaIn) nanoparticles are formed. In these embodiments, the bulk liquid alloy is ultrasonically dispersed, fast thiolate self-assembly at the EGaIn interface protects the material against oxidation. The assembly shell has been designed to include intermolecular hydrogen bonds, which induce surface strain, assisting in cleavage of the alloy particles to the nanoscale. X-ray diffraction and TEM analyses reveal that the nanoscale particles are in an amorphous or liquid phase, with no observed faceting.
