Abstract:
DESCRIPTION (Applicant's abstract verbatim): The objective of this proposed
research is to construct a prototype neutron microscope capable of imaging
biological maternal. By using compound refractive lenses recently developed by
Adelphi Technology microscopy is possible with imaging distances in the order
of a few meters. Neutron microscopy can be a valuable complement and extension
of already mature light, x-ray and electron imaging techniques. Unlike these
other sources, neutron propagation in matter is defined by strong
neutron-nucleus interaction. Neutrons can provide a means to probe into
materials with a completely different "light" allowing visualization of objects
otherwise concealed. Biological molecules are ideal for imaging with neutrons,
as their hydrocarbon constituents would provide excellent image contrast.
Thicker, unstained, unfixed, in vivo samples may be imaged with neutrons since
they are less affected by absorption than other sources thus, reducing
artifacts created by sample preparation. Also, achievable resolutions of
neutron microscopy surpasses those attained with visible light and x-rays, down
to few Angstroms making it possible to directly image viruses and genes. The
potential for successful development of the prototype imaging system is very
high because our preliminary experiment with compound refractive lenses has
demonstrated thermal neutron collection and focusing. The research will proceed
by optimizing the design of these lenses for imaging and, then, experimentally
demonstrating image magnification of biological materials. Neutron microscope
designs will include commercially available compact neutron sources for
clinical and laboratory use.
PROPOSED COMMERCIAL APPLICATION:
The development of neutron lens of short focal length would be truly revolutionary since
such a lens could be utilized in a large number of applications related to imaging biological
materials. Neutron microscopy will permit high-resolution, high-contrast imaging of soft
tissue. Unlike x-ray imaging, which achieves contrast with high atomic number atoms,
neutron imaging will give contrast with low atomic number materials.
