Nanofibrous scaffolds provide high surface area for cell attachment, and resemble the structure of the collagen fibers which naturally occur in the basement membrane and extracellular matrix. A label free and non-destructive method of assessing the interaction of cell tissue and scaffolds aids in the ability to discern the effective quality and magnitude of any scaffold modifications. Impedance cell spectroscopy is a biosensing method that employs a functional approach to assessing the cell monolayer. The electrical impedance barrier function of a cell monolayer represents the level of restriction to diffusion of charged species between all adjacent cells across an entire …

Epidemiology & Biostatistics Faculty Scholarship
Digital mammography saw rapid adoption during the first decade of the 2000s. According to data maintained by the Food and Drug Administration, which regulates mammography machines, fewer than 1 percent of the machines in 2001 were digital. By 2014, this figure had risen to 94%. We were interested in identifying the times and locations where the technology was introduced within the state of New York as a way of illustrating the uneven introduction of this technology. While the diffusion of medical innovation has been well-studied, there have not been many instances where maps or geographic information science methods have been …
