Professor Yuzhuo Li Investigates Methods for the Preparation and
Application of Biosensor Liposomes
Yuzhuo Li and his research group are investigating methods for the
preparation and application of novel liposome systems using triblock
copolymers. The new liposome systems are designed to incorporate
functionalities that can be used for rapid enzyme and receptor assays
for biosensor technology. The biosensor can detect molecular recognition
events with minute concentration. This device is potentially useful
for the monitoring of the change of biological species in an environment
and as a tool to screen drug candidates such as enzyme and receptor

Professor Dan Goia Prepares Metallic Particles for Potential Use
in Defense Related Applications
Dan Goia is preparing metallic particles for potential use in defense
related applications such as obscurant smokes, electromagnetic interference
shielding, bio-medical applications, and in energy generation devices.
These areas are briefly described.
smokes. Smoke clouds consisting of fine particles are known
to be capable of preventing the detection of military equipment
by a combination of radiation scattering or absorption. While in
the visible spectrum both metallic and dielectric particles can
act as very effective screens. In the very important range of near
and infrared wavelengths, the highly conductive metallic particles
are the ideal materials. Theoretical work by the Army scientists
indicates that a high aspect ratio, highly conductive metallic particles
(fibers, flakes) having at least one nanoscale dimension are desired.
Consequently, Au, Ag, Cu, and other highly conductive metals in
form of flakes or fibers can be especially effective for such purposes
- either in a pure state or deposited as coatings on non-conductive
substrates, which already possess the desired morphology.
Interference (EMI) Shielding. The importance of the capability
to effectively protect defense related channels of communication,
especially in the light of the recent terrorist attacks, couldn't
be understated. Fine metallic particles of highly conductive elements
or alloys (Ag, Au) are already used in the telecommunication industry
to provide very effective EMI shielding by serving as precursors
for continuous, dense, and electrically conductive metallic barriers
and it is likely that they will find similar applications in the
area of defense.
applications. Metallic particles can also be used in many
applications, which can be adapted to ensure the protection of the
personnel involved in combat situations. For example, micron size
spherical Au particles can be used for trans-dermal vaccination
('powder vaccine method') while nanosize Au particles can act as
a vector to deliver drugs or antidotes against chemical and bacteriologic
agents. Both situations could be highly useful in developing individual
kits to administer drugs simply and safely in remote or isolated
locations. Nanosize silver particles are known to be an excellent
antibacterial agent and, consequently, can be used to ensure personnel
hygiene (equipment, food and water supply) as well as safe emergency
medical operations (mobile hospitals, emergency surgical kits, etc.)
in infested environments.
generation. Nanosize metallic particles (Pt, Pt/Ru alloys)
are the materials of choice for manufacturing the electrocatalysts
for PEM fuel cells that can be used to provide the necessary energy
for the mobile devices (communication, heat supply) carried by soldiers
in order to stay operational yet undetected in hostile environments.
