COVER PAGE on Lab Chip Journal Issue 23, 2011
-
On the cover of Lab Chip journal
(impact factor: 6.3) our recent work has been highlighted
with an image describing our method for droplet combination
in microfluidic devices that allows passive parallel
synchronization. They describe the layout as being analogous
to a train track, as the network consists of a top channel,
a bottom channel, and ladder-like connections between the
two main channels. It has also been highlighted on the LOC
blog at http://blogs.rsc.org/lc/.

BRINGING PHYSICS & ENGINEERING TO LIFE" in Spring 2011 (DISCOVERY
SEMINAR COURSE)
- Instructors:
Professors
Markelz (Physics, UB), Oh (Electrical Eng, UB),
and Snell (Structural Biology, HWI)
-
Highlights: You will see how biology is studied from three
very different view points: Prof. Markelz is a physicist and
she is looking for fundamental physical properties using
optics, Prof. Oh is an electrical engineer who
designs and fabricates microfluidic systems for manipulation
of biological samples and Prof. Snell is a structural
biologist who is studying the relationship between the
structure of proteins and what they do and how to prevent
bad things from happening.
