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.

There is currently no radiotherapy phantom capable of quantitatively assessing all components of an online adaptive radiotherapy (online ART) system in a comprehensive end-to-end test.Represented here is a novel, rigid phantom that can simultaneously evaluate an online ART system's image acquisition, deformable image registration, contour propagation, plan re-optimization, dose calculation, and beam delivery in a single process that is robust, quantitative, and convenient.

A new approach for obtaining less invasive optical measurements of the cervix has been developed that does not require the use of a speculum exam. This technology can visualize the cervix in vivo to find unique biomarkers that indicate various conditions such as preterm labor, cancer, human papillomavirus (HPV), and dysplasia.

The standard for kidney stone detection is through the use of computed tomography (CT). However, CT is expensive and delivers harmful ionizing radiation into the body. Ultrasound would be the ideal way to detect kidney stones except that it performs poorly in detecting and accurately sizing stones. Vanderbilt researchers inventors have developed a technique that is able to separate hard, mineralized material (i.e kidney stones) from soft tissue in a way that is both cheaper and safer than CT and performs better than conventional ultrasound imaging.
