The article Tiny self-assembling cubes could carry medicine, cell therapy said
Johns Hopkins researchers have devised a self-assembling cube-shaped perforated container, no larger than a dust speck, that could serve as a delivery system for medications and cell therapy.
The relatively inexpensive microcontainers can be mass-produced through a process that mixes electronic chip-making techniques with basic chemistry. Because of their metallic nature, the cubic container’s location in the body could easily be tracked by magnetic resonance imaging.
“Our group has developed a new process for fabricating three-dimensional micropatterned containers for cell encapsulation and drug delivery”, said David H. Gracias, who led the lab team. “We are talking about an entirely new encapsulation and delivery device that could lead to a new generation of ‘smart pills’. The long-term goal is to be able to implant a collection of these therapeutic containers directly at the site or an injury or an illness.”
Dr. David H.
Gracias
was born in 1972 in Bombay, India. He completed his undergraduate studies
at
The Indian Institute of Technology (IIT), Kharagpur where he
completed a 5 year Integrated M.S. in 1994. He moved to the
US for graduate studies in 1994 where he received his Ph.D. in Physical
Chemistry from the University of California at Berkeley and the Materials
Science Division of Lawrence Berkeley National Laboratory.
After completing his Ph.D., David was a post-doctoral fellow at Harvard
where he demonstrated biomimetic strategies for forming
functional electronic devices using surface modification and
self-assembly. Subsequently he was employed as a Senior Engineer in
Research and Development at Intel Corporation, where he was responsible
for integrating new processes for fabricating logic (digital) processors
and mixed signal (analog + digital) communication chips at the 45nm-90nm
nodes.
He joined the Department of Chemical and Biomolecular Engineering at Johns Hopkins University in August 2003. His research interests lie
in
the
areas of Micro and Nanotechnology, Self-assembly, Non-Linear Optics,
Nanoelectronics, Interfacial Science, Biomedical Devices and
Nano-Medicine.
David has published 25
research
papers, holds 6 US patents (over
10 patents pending) and has given 20 invited talks in the research areas
listed above. His patents include “Adhesion of carbon doped
oxides by silane coupling agents in damascene integration of
microelectronic devices”, “Reducing line to line capacitance
using oriented dielectric films”, “Protecting metal conductors with
sacrificial organic monolayers”, and “Method to increase electromigration resistance of
copper using self assembled organic thiolate monolayers”.
In 2005, he received the National Science
Foundation (NSF)
CAREER
award — the foundation’s most prestigious
award
for
new faculty members. The award recognizes and supports the early career
development activities of those teacher-scholars who are most likely to
become the academic leaders of the 21st century.
Lifeboat Tidbit: Gracias has the connotation of “gracious” in
Portuguese. Many people
are curious how a person from India might be named David Gracias. David’s
lineage is from Goa, a region on the west coast of present day India
bordering the Arabian Sea. Goa was the capital of the Portuguese empire
in the East from 1510 to 1961. Since 1961 Goa has become a part of India.
