Motor proteins such as kinesin move along microtubules in order to transport cellular cargos throughout the cell by obtaining energy from RNA hydrolysis which allows the cell to complete the tasks needed to stay alive. In this work, we developed synthetic molecular motors using DNA enzymes (DNAzyme) and fluorescent nanomaterials which mimic the functions and structures of motor proteins. A DNAzyme-capped CdS nanoparticle and a RNA-functionalized single-walled carbon nanotube (SWCNT) were used as a walker and a track in the motor platform, respectively. As a walking mechanism, the DNAzyme cleaved the RNA substrates in the presence of metal cations. The …

Ischemic stroke is the world's second leading cause of death and accounts for 2-4% of total worldwide healthcare costs. Ischemic stroke is caused by the occlusion of arteries responsible for supplying blood to the brain, which can result in disability or death. Arterial blood clots consist of aggregates of activated platelets wrapped in a mesh of fibrin. Tissue plasminogen activator, the only current FDA-approved treatment for ischemic stroke, functions by lysing fibrin in a blood clot. Unfortunately, tissue plasminogen activator significantly increases bleeding risks, which restricts its use. Alternatively, targeting and disrupting platelets within a clot could improve stroke outcome. …

Approximately 90% of all cancer related deaths can be attributed to the occurrence of metastasis. There are multiple changes that occur within the tumor microenvironment that have been correlated with the onset of metastasis. Different cell types, extracellular matrices, blood vessels, and soluble factors are some of the various components that make up the complex, heterogeneous microenvironment that exists within a tumor. The dynamic relationship between tumor cells and their surrounding environment makes it an ideal environment to study triggers of metastasis, such as the modification of the extracellular matrix. Changes in the multiple aspects of extracellular matrix composition have …
