Vanderbilt researchers have created a new multi-organs-on-chip platform that comprises Perfusion Control systems, MicroFormulators, and MicroClinical Analyzers connected via fluidic networks. The real-time combination of multiple different solutions to create customized perfusion media and the analysis of the effluents from each well are both controlled by the intelligent use of a computer-operated system of pumps and valves. This permits, for the first time, a compact, low-cost system for creating a time-dependent drug dosage profile in a tissue system inside each well.

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.
