Vanderbilt inventors have developed a one-step hydrosilylation synthesis of azide surfaces for the preparation of click chemistry compatible substrates. In this process, an organic azide is formed in a single step on a hydrogen-terminated silicon support, yielding a surface that is ready to undergo click reactions as desired. Simple, efficient, and versatile, click chemistry is widely used and is particularly useful for biosensing applications. A click reaction can be utilized to attach a molecular or biological probe for point-of-care diagnostics and chemical screening.

Vanderbilt researchers have synthesized porous adsorbent materials for the capture of toxic industrial chemicals. These adsorbent materials have finely dispersed reactive sites that allow for higher adsorption capacities than existing materials. They can be used in filters for the military, homeland security, first responders, and for a wide range of industrial and commercial catalysts to capture toxic gases such as ammonia and sulfur dioxide.

Phase change materials (PCMs) are a fascinating class of materials that can change certain material properties (e.g., absorbance or reflectivity) upon the application of a stimulus. Researchers at Vanderbilt University have used a PCM to create a novel metamaterial that can be reconfigured for use in a wide range of potential optical and integrated photonic applications from the infrared to terahertz spectral domain.
