We have developed a number of approaches for cell manipulation spanning 
from polyelectrolyte multilayer (PEM) microfluidic patterns to 
dielectrophoretic (DEP) trapping in microfluidic multilayer systems.The 
electrostatic interactions between PEMs and cells have shown excellent 
results as a "universal glue" for cell attachment in our fluid flow 
field systems.We have engineered a hybrid cell adhesive material (hCAM) 
and integrated in a microfluidic system with DEP trapping forces 
resulting in rapid cell adhesion.Moreover, cell viability and function 
were maintained under DEP conditions.This system has also shown promise 
for the development of multilayer microfluidic devices, where cells can 
be trapped on opposite sides of a permeable polyester (PET) membrane 
that separates two channels running perpendicular to each other.These 
approaches can be used for studies such as cell-cell communication, cell 
migration and many other applications.

Dr. Reyes is a principal investigator in the Nanoscale Metrology Group 
in the Semiconductor & Dimensional Metrology Division of the Physical 
Measurement Laboratory (PML) at the National Institute of Standards and 
Technology (NIST).He received his Ph.D. and B.S. in chemistry from the 
University of Puerto Rico.He also received a M.S. in Applied Biomedical 
Engineering from The Johns Hopkins University.His research history 
covers diverse scientific fields, i.e., from toxicology and 
environmental analytical chemistry, to biomedical engineering and 
microfluidic systems.In his doctoral work, he chemically characterized 
airborne particulate matter from an area in Puerto Rico of high 
incidence of cancer, asthma, and other respiratory diseases, using 
cell-based toxicological assays.After completing his Ph.D. he was 
awarded with a National Science Foundation Postdoctoral Fellowship to 
work with Professor Andreas Manz at Imperial College, London, U.K.During 
this postdoctoral experience, he worked with microfluidic devices in 
developing two-dimensional separation systems and analog computing using 
glow discharge in microfluidic chips.

Dr. Reyes joined NIST as a National Research Council postdoctoral 
fellow.There he started integrating his previous research experiences in 
cell-based measurements and microfluidics with electronics manipulation 
and measurements developing bioelectronics-related technology.Dr. Reyes 
has been developing microfluidic devices with integrated 
dielectrophoretic manipulation for long-term cell survival, and recently 
he started working towards the development of measurement tools for 
dynamic forces in mechanobiology.Overall, his work has been cited more 
than 2,700 times.At NIST, his work has been funded through various 
intramural programs including Advanced Technology Program (ATP), 
Director's Reserve Funds, and Innovations in Measurement Science (IMS) 

Dr. Reyeswas the co-chair of the 1st Annual Diversity Day celebrated at 
NIST in 2006 and was awarded the NIST EEO Diversity Award (2008) for his 
contribution in organizing that event. He was also an executive 
committee member of the NIST Sigma Xi Chapter.Dr. Reyes is currently a 
member of the Nanoparticle Safety Committee as well as the NIST 
Biosafety Committee.


*NSF Seeks Representatives for Advisory Committees*

[Adapted from an email message that I received. SGN]

The National Science Foundation (NSF) requests recommendations for 
membership on its scientific and technical federal advisory committees. 
Self recommendations are accepted. Committee members serve varying term 
lengths. NSF has 13 scientific and technical advisory committees, including:

Advisory Committee for Education and Human Resources [some members' 
terms expire May 30, 2014]

Advisory Committee for Computer and Information Science and Engineering

Advisory Committee for Cyberinfrastructure

Advisory Committee for Mathematical and Physical Sciences

Advisory Committee for International Science and Engineering

Committee on Equal Opportunities in Science and Engineering

*New NSF Mathematical Sciences Innovation Incubator*

[Adapted from an email message that I received. SGN]

The National Science Foundation (NSF) Division of Mathematical Sciences 
(DMS) aims to enhance the synergistic relationships between the 
mathematical sciences and other NSF-supported disciplines through the 
Mathematical Sciences Innovation Incubator (MSII) activity. The MSII 
activity encourages and supports new research collaborations among 
mathematical scientists and other scientists and engineers working in 
NSF-supported research areas of high national priority by:

  * facilitating DMS co-review and co-funding of multi-disciplinary
    research collaborations involving mathematical scientists;
  * providing leverage for investments of non-DMS NSF programs in
    projects that include mathematical scientists; and
  * providing a uniform mechanism through which collaborative research
    teams involving mathematical scientists can request DMS co-review.

The ideas, tools, and language of mathematics and statistics play 
important roles in every area of science and engineering research 
supported by the NSF, and it is widely recognized that interactions 
between the mathematical sciences and other fields catalyze developments 
in both.

... The Division of Mathematical Sciences wishes to foster the 
participation of more mathematical scientists, from every area of 
mathematics and statistics, in such important interdisciplinary work. In 
support of this goal, the MSII activity provides funding to catalyze the 
involvement of mathematical scientists in research areas where the 
mathematical sciences are not yet playing large roles.

The MSII activity will emphasize scientific research areas of high 
national priority that would benefit from innovative developments in 
mathematics and statistics. ... Areas of national high-priority 
scientific research in fiscal year 2014 identified by the U.S. Office of 
Science and Technology Policy include:

  * Advanced Manufacturing
  * Clean Energy
  * Global Climate Change
  * Research and Development for Informed Policy-Making and Management
  * Information Technology Research and Development
  * Nanotechnology
  * Biological Innovation

National Science Foundation programs addressing these areas of national 
priority in which mathematical scientists are not yet playing large 
roles are listed on the MSII web page:

To apply for MSII support, after submitting a proposal to a non-DMS 
program for a research project that involves mathematical scientists, or 
a supplement request to include new mathematical scientists in a 
research project supported by a non-DMS award, the Principal 
Investigator must send an e-mail message specifying the name(s) and 
affiliation(s) of the mathematical scientist(s) and the NSF proposal ID 
to [ [log in to unmask] ]. Transmission of this e-mail message will 
constitute a request that DMS consider the proposal or supplement 
request for MSII funding.


*Qiliang Li Receives Funding from NIST*

Qilian Li of the Electrical & Computer Engineering Department received 
$50K from the National Institute of Standards and Technology for his 
project, "Two-Dimensional Atomic Crystal Field Transistors with 
Ultra-High Sensitivity."
