In the past, we studied for the
first
time thermophoresis of DNA, i.e. fast movement of
DNA from hot to cold in a
temperature
gradient. It can be used to accumulate DNA
million-fold by thermal
convection.
A similar convection flow was later used to
implement a fast and small DNA
replicating
PCR
reaction.
Both experiments are the
foundation
for new biotechnological approaches to diagnostics.
At the same time they show new
ways
for hypothesis on the origin of life in pores of
vulcanic rock at the ocean
seafloor.
We will continue to explore new
basic
effects of microscopic temperature fields. For
example we want to use a
sinusoidal
temperature
oscillation to yield a lock-in based
frequency space approach for
kinetic
measurements inside cells.
Stefan Duhr and Philipp
Baaske have founded the startup company NanoTemper Technologies
for thermophoretic and optical
melting curve analytics.
