Semiconductors · Henrietta, United States · Founded 2007

Innovators in Silicon Nanomembranes and BioMEMS Technologies for Precise Specimen and Data Capture MoreLess

SiMPore, Inc. is a nanotechnology materials company established in 2007. The firm was co-founded by James L. McGrath, Thomas Gaborski, and James Roussie. McGrath, a Professor of Biomedical Engineering at the University of Rochester, has been leading the Nanomembrane Research Group since 2007, and his academic work is foundational to SiMPore's commercial manufacturing of nanomembranes. Roussie serves as the Chief Scientific Officer, applying his Ph.D. in Biochemistry to technology commercialization, product development, and intellectual property management.

The company operates in the life sciences and materials science markets, developing and commercializing ultrathin silicon-based membranes. Its business model involves the direct sale of these specialized products to researchers and scientists, facilitated through its primary website and the subsidiary site TEMwindows.com, which focuses on sample preparation solutions for imaging and analysis. SiMPore also utilizes a global network of distributors to reach its international client base.

SiMPore's core technology leverages proprietary etching methods to produce silicon nanomembranes that are significantly thinner than conventional alternatives, ranging from 15 nm to 400 nm. This reduced thickness allows for greater permeability and higher resolution in separation and filtration tasks. The product portfolio includes a variety of TEM grids, filters, and cell culture substrates designed for the precise capture and analysis of nanoscale materials. Specific products include porous membrane chips, X-ray windows for microscopy and spectroscopy, and filters for separating nanoparticles and biological molecules. These tools enable clients in biomedical and materials science to achieve more accurate data collection for applications ranging from microplastic analysis to developing tissue-on-a-chip models.
