CAMP Professor Dan Goia is involved in the synthesis,
characterization, and modification of ultra-fine and nanosize metallic
and metal-composite particles with controlled size, shape, internal
structure, composition, and surface properties. Besides being already
used extensively in catalysis, electronics, metallurgy, and pigments,
these materials could have a significant impact in many emerging
technological fields such as medicine, biology, defense, nonlinear
optics, energy generation, and magnetic storage. Professor Goia
also has several active government and industrial grants to conduct
research in the areas of metal and metal-composite particles for
defense applications, heterogeneous metallic catalysts for PEM (Proton
Exchange Membrane) and solid oxide fuel cells, precious and base
metal powders for electronic components, metallic flakes for electromagnetic
interference shielding, nanosize metallic particles for medical
and antimicrobial applications, and metal composite powders for
1: Highly dispersed nanosize (~70 nm) silver particles. A novel
precipitation process capable of producing reproducibly and cost-effectively,
highly- dispersed and uniform silver nanoparticles (10 -100 nm)
was recently developed in Professor Dan Goia's research laboratory.
These materials have already been tested successfully in electronic,
medical, decorative, and biological applications. The technology
was licensed by NanoDynamics Inc. (Buffalo/NY) and the scale up
effort is presently underway.
As a result of the research conducted under these
grants, Professor Goia has already developed several novel technologies
to manufacture fine, ultra-fine, and nanosize dispersed metallic
particles and flakes for electronic, catalytic, metallurgical, and
biological applications. (See Figure 1.)
The intellectual property rights for four of these technologies
were already acquired by two of CAMP's industrial partners who have
scaled up the respective processes and have introduced several new
products into these markets.
Professors Fendler and Roy Study Nanostructured Layered Materials
for Potential Use in Biological and Chemical Sensors
In a collaborative project, CAMP Professors Janos Fendler (CAMP
Distinguished Professor of the Chemistry Department) and Dipankar
Roy are studying multilayered thin films that are composed of highly
ordered nanomaterials. These films are fabricated by using the technique
of self-assembly. Molecular self-assembly is now widely recognized
as a cost-effective approach to nanofabrication of biomaterials.
It often involves relatively simple and well-developed chemical
techniques, and at the same time, can provide highly ordered molecular
nanostructures that are precisely tailored with desired chemical
properties and complex functionalities.
Research in this area by the CAMP groups is continuing, and it
is expected that the new results will considerably ease the difficult
task of designing nanoparticle-based high performance SPR biosensors.
Currently Professors Fendler and Roy are attempting to combine FFT-EIS
with the SPR technique. Their goal is to eventually achieve new
types of opto-electrochemical biosensors that would have much broader
capabilities than the currently available sensors based on single
lists of recently published research reports from Professors Fendler's
and Roy's groups can be found at the following websites:
