Zinc sparks induce physiochemical changes in the egg zona pellucida that prevent polyspermy

EPIC Biocryo facility manager Reiner Bleher and Biocryo specialist Eric W. Roth recently co-authored a paper published in the journal Integrative Biology. Using EPIC's SEMs and TEMs, the research team led by Northwestern scientists Theresa Woodruff and Thomas O’Halloran was able to show the previously unknown role of zinc in hardening the tissue surrounding a fertilized egg cell.

Electron Probe Instrumentation Center (EPIC)


Welcome

EPIC houses instruments for scanning electron microscopy (SEM), transmission electron microscopy (TEM) including scanning transmission electron microscopy (STEM), cryo electron microscopy (BioCryo), focused-ion beam (FIB) and specimen preparation facility (SPF). EPIC jointly collaborates with the Quantitative Bioelemental Imaging Center (QBIC) core facility as well.

EPIC receives support from the Soft and Hybrid Nanotechnology Experimental (SHyNE) Resource (NSF ECCS-1542205); the MRSEC program (NSF DMR-1121262) at the Materials Research Center; the International Institute for Nanotechnology (IIN); and the State of Illinois, through the IIN.  EPIC houses one of the most complete arsenals of routine and state-of-the-art electron microscopes in the world.


Mission

The primary objective of our mission is to enhance the education, collaboration, research and outreach related to all aspects of electron probe instrumentation, techniques and applications.  EPIC is a shared user facility that supports a broad range of nanoscale science and technology projects, specializing in nanoscale analysis and characterization.

EPIC is a multi-user, multi-departmental facility offering continually updated state-of-the-art equipment to qualified researchers from any field and institution.  EPIC has a strong tradition of facilitating interdisciplinary research, and regular training sessions and short courses are offered by accomplished microscopists who manage the EPIC facility, directed by Professor Vinayak P. Dravid.


Research and Societal Outreach

EPIC facility staff members routinely collaborate with Northwestern faculty and students on research that have been published in journals such as Science, Nature Materials and Nanotechnology.

EPIC maintains vibrant partnerships with academic and cultural institutions in the greater Chicago region, such as the Art Institute of Chicago. These efforts regularly culminate in the publication of research in prominent journals specific to the fields served by these institutions.

EPIC consistently works in concert with industrial partners such as British Petroleum, Nanosonics, Baxter, Hitachi, Cabot Microelectronics, Carpenter, Chugai, JEOL, Battelle, EBeam Devices, Avery Denison, Kraft Inc. as well as many others.

Local teachers, museums and members of the community are encouraged to join the NUANCE family through open house visits, demonstrations and presentations on how nanotechnology affects our daily lives. To schedule a tour for your group, please contact us.
