Selective Transport Through Well-Defined Dendrimeric


Professor Richard M. Crooks




Polymeric materials are commonly used to control mass transfer between liquid
phases and surfaces to prevent corrosion or to selectively pass ions in energy
producing devices and chemical sensors. Polymers are also useful for enabling
gas separations. Applications such as these are of tremendous importance to
industry, and even modest improvements in performance can yield dramatic effects
on the economic competitiveness of businesses and nations. It is not surprising,
therefore, that scientists and engineers in academics, government laboratories,
and industry dedicate substantial resources to the development of new polymeric
materials that offer enhancements for small molecule discrimination. This
presentation is about dendrimers and how they can be used to prepare exquisitely
selective nanoscopic chemical filters. Dendrimers, which were first reported by
Vögtle in 1978, are nearly monodisperse (and sometimes truly monodisperse)
polymers with well-defined geometrical and chemical structures. Because of their
uniform properties, dendrimers, and related materials such as hyperbranched
polymers, provide a valuable model for correlating macromolecular structure to
technological function. Proof of concept experiments focusing on chemical
sensing and catalysis that demonstrate the principle of molecular filtering will
be described in this talk.


Biographical Sketch


Richard M. Crooks received a B.S. degree in chemistry from the University of
Illinois and a Ph. D. in electrochemistry from the University of Texas (Austin)
in 1987. Following a two-year postdoctoral appointment at MIT, he moved to the
University of New Mexico in 1989 and then to Texas A&M University where he
is currently professor of chemistry and director of the Center for Integrated
Microchemical Systems with interests in chemical sensors and interfacial design,
microfluidic devices, catalysis, electrochemistry, and transport in nanoscopic
domains. He has published more than 150 research papers.


Plastic Microstructures for Optical and Drug-Delivery


Professor Liwei Lin

Department of Mechanical Engineering University of California
Berkeley, California 947201 USA


In the past twenty years, the application of microelectronic technology to
the fabrication of mechanical devices stimulated emerging research in
semi-conductor microsensors and microactuators. The versatility of semiconductor
materials and the miniaturization of VLSI patterning techniques promise new
devices with better capabilities and improved performance-to-cost ratio over
those of conventionally machined devices. This talk will introduce the methods
of applying micromachining technologies to fabricate polymer-based structures
and their applications. Examples and applications in different subject areas
related to optical and drug-delivery applications will be described such as
materials, fabrication processes, performances and commercial potentials.
Specific devices to be discussed include a plastic thin film with millions of
built-in micro pyramids for brightness enhancement applications, a cylindrical
microlens for optical communication applications and a water-powered drug
delivery system. Various design and manufacturing issues will be introduced to
explain the make of these devices including bulk-micromachining, and plastic
molding processes of hot embossing and injection molding.

Biographical Sketch

Professor Liwei Lin received the M.S. and Ph.D. degrees in Mechanical
Engineering from the University of California, Berkeley, in 1991 and 1993
respectively. He joined BEI Electronics Inc. USA from 1993 to 1994 in research
and development of microsensors. From 1994 to 1996, he was an Associate
Professor in National Taiwan University, Taiwan. From 1996 to 1999, he was an
Assistant Professor at the University of Michigan. He joined the University of
California at Berkeley in 1999 as an Associate Professor at Mechanical
Engineering and Co-Director at Berkeley Sensor and Actuator Center, an
NSF/Industry/University research cooperative center. His research interests are
in design, modeling and fabrication of microstructures, microsensors and
microactuators as well as mechanical issues in microelectromechanical systems
including heat transfer, solid/fluid mechanics and dynamics. Dr. Lin is the
recipient of the 1998 NSF CAREER Award for research in MEMS Packaging and the
1999 ASME Journal of Heat Transfer best paper award for his work on micro scale
bubble formation. He led the effort in establishing the MEMS sub-division in
ASME and is currently serving as the Vice Chairman of the Executive Committee
for the MEMS sub-division. He holds 7 U.S. patents in the area of MEMS.
