| The emerging
fields of nanoscience and nanoengineering are leading to unprecedented
understanding and control over the fundamental building blocks of all physical
things. This is likely to change the way almost everything—from vaccines to computers
to automobile tires to objects not yet imagined—is designed and made. It is
anticipated that a new world of industrial products valued at $1trillion/yr
and, at least, 2 million nanotech workers would emerge in 10-15yrs. In order to
be part of this exciting ‘Nano world’, CAMD has established nanofabrication
facility, taking advantage of the well established infrastructure for microfabrication
and X-ray absorption spectroscopy. The core competency of the ‘nanofabrication’
research group is to synthesize variety
of nanoparticles,
characterize them using X-ray absorption spectroscopy and utilize them to
fabricate devices for biomedical applications. A wet chemical laboratory was
commissioned to synthesize metallic mono, bi and core-shell metallic/polymer nanoparticles
using techniques such as reverse micelle, sonochemical and surfactant mediated
classical reduction. The facility utilizes in-house X-ray absorption
spectroscopic techniques for characterization of nanoparticles. EXAFS ( X-ray
Absorption Fine Structure ) and XANES ( X-ray Absorption Near Edge Structure )
are unique tools and are being used to determine electronic and geometric
structures of metallic nanosystems, where the absence of long range order makes
standard techniques such as X-Ray Diffraction less reliable. Utilizing
appropriate nanoparticles, functional micro/nano devices are being fabricated
using well established LIGA technique.
The motto of the facility
is fostering interdisciplinary research. Researchers/students working
in the facility would be exposed to variety of techniques in nanotechnology,
organic chemistry, bio-chemistry, polymer science, material science,
X-absorption spectroscopy and micro fabrication. The facility has
active collaborations with departments of chemistry, physics, biological
sciences, chemical engineering, mechanical engineering of Louisinana State University
( Baton Rouge ), Pennington Biomedical Research Center
( Baton Rouge ), Advanced
Materials Research Institute ( New Orleans ), Institute of Physics
( Bonn, Germany ) Max-Planck
Institute for Kohlenforschung ( Mulheim, Germany ).
Nano Fabrication
Facility is also geared up for active collaboration with industry and those
interested may contact CAMD management. The facility can provide stable Pd, Pt,
Co, Rh, Ru, magnetite, bimetallic alloy or core-shell nanoclusters, compatible
with nonpolar as well as polar solvent systems, for research purposes to
interested customers.
Researchers/students
are encouraged to use the facility after obtaining approval by the CAMD
management and training in safety & laboratory procedures.
