DESCRIPTION:The design and behaviour of artificial microswimmers has garne
 red significant research interest in recent years. Potential applications 
 such as controlled drug-delivery make them a very promising tool once perf
 ected. However\, the vast majority of current designs suffers from a commo
 n problem: the swimmers remain in the fluid indefinitely\, posing risks of
  clogging and damage. Inspired by recent design proposals\, we investigate
  the dynamics of a degradable microswimmer. In this seminar\, we will give
  an introduction to the stochastic calculus necessary for the description 
 of a colloid with slowly varying diffusivity\, and use this to present and
  compare three models of the decay of a swimmer\, taking into account the 
 nature of the chemical reaction at its surface. From this we can draw valu
 able conclusions about the practicability of a wide range of materials for
  the design of such a colloid.\n
