Orientation |
Why is
the scientific problem of interest at all? Self-motile microscopic swimmers such as bacteria are
capable of directed motion through a fluid in response to, e.g. a chemical
gradient. For such micron-sized
objects the combination of low ReynoldÕs number and
Brownian motion determine the swimming strategy that will be effective and
the swimmerÕs trajectory. |
How |
How is
the research going to shed light on the given problem?. Recently,
several artificial microswimmers have been
demonstrated that are powered by asymmetric chemical reactions. These have been suggested as both
model systems for the understanding of motile cells, and as tools for pick-up
and delivery of nano-scale objects. |
What |
What is the specific
thing that the student will do, and how does it fit inside the overall
project? The aim of this project is to model
the dynamics of such autonomously-propelled Ôactive
colloidsÕ in response to a structured environment and their interactions with
other microswimmers. |
Special Knowledge |
This project will require strong
programming skills (in, e.g. Matlab). |
