“The breadth of KU research
provided me with in-house
collaborators for the project,
which streamlines the
development of a two-photon
microscopy system,” says
Hui. “There is a great need for
accessible biological imaging
tools. TP-FLEX, which will
be the size of a briefcase, will
enable two-photon microscopy
to become available to those
outside large research centers.”
EECS Ph.D. student Peter Adany adjusts a spectrum analyzer during testing
of the optical fiber, the yellow cable. Adany observes how the fiber reacts
in different situations and then creates computer simulation models to
predict future behavior.
The KU system will permit
the simultaneous monitoring
of different biochemical
functions through multicolor
labeling. With bioflourescent
markers attached to specific
proteins, various protein and
molecular configurations can
be distinguished and observed.
Thus, scientists can observe
multiple cellular events at the
same time.
EECS researchers are
collaborating with investigators
from KU’s Department of
Chemistry and the KU Medical
Center on the “Portable and
Wavelength-Tunable Two-
Photon Microscopy” project.
The lower cost and portability
of TP-FLEX will enable greater
accessibility for a wide range
of biological, chemical, and
analytical applications.
The fiber turns fluorescent as light travels through it.
By understanding and controlling the generation of
optical pulses, researchers can produce 3D images of
living cells at greater depths and higher resolutions.
