Core Technologies
NCMIR pursues a coordinated, three-pronged
approach to achieving its goals of imaging biological
systems on a grand scale, focusing core technology
development in three areas.
- biological specimen development for intermediate
voltage electron microscopes (IVEMs) and correlated microscopies
- instrumentation, including IVEM, camera development,
and Telemicroscopy
- advanced software infrastructure applications
and database development
Biological Specimen Development
for IVEM
NCMIR is building on continued success in
developing contrast-enhancing methods, particularly
in the area of fluorescence photooxidation of recombinant
proteins, for biological specimens that will clearly
benefit from the unique capabilities of computer-coupled
microscopes. These technologies use correlated light
and electron microscopies for large-scale imaging,
spanning the dimensional range and scale of tissue
organization to macromolecular specializations of
cellular microdomains.
Imaging Instrument Development
The combination of intermediate voltage electron microscopy and
electron microscopic tomography remains a focus of NCMIR. With the
increasing emphasis on multi-scale integration in biological systems,
however, NCMIR has been expanding its activities in correlated microscopy,
integrating multi-photon light and ultra high-voltage electron microscopic
techniques to accommodate the multi-scale studies being driven by
collaboration. To support ultra wide-field imaging, NCMIR continues
to build on the success of its ultra large-field lens-coupled CCD
camera technologies, pushing the resolution and performance of state-of-the-art
digital detectors for high-voltage electron microscopy. As each
resource instrument is improved to deliver unique and important
new capabilities, each is also being integrated with leading-edge,
grid-service-based technologies for generalized Telemicroscopy.
Advanced Software Infrastructure Applications
and Database Development With the development of the Telescience Portal,
NCMIR has made significant contributions in the area of grid-enabled
environments for end-to-end electron tomography. Many applications
have been rewritten in Java and/or modified for web-based operation
within a globally distributed grid environment. The Cell Centered
Database (CCDB), a sophisticated web-based database management system
for 3D microscopies, serves multiple functions, as a data management
tool for the resource, as a means to disseminate and share data
produced at NCMIR, and as one of a series of linked and federated
databases across multiple biological scales as part of the BIRN
and Telescience projects.
