Elastin like peptides undergo an inverse temperature transition. So the peptide will fold upon heating. Simulations indicate that this transition leads to a significant change of the radius of gyration. With small angle neutron scattering this quantity is easily accessible and can be followed over a wide range of temperature. In the proposed experminet we intend to study this transition in bulk and in a soft confinement. The confinement is provided by a microemulsion in the droplet phase. By an appropriate deuteration scheme the scattering contrast will be mainly between the peptide and its background. Thus it will be possible to follow the inverse temperature transition, even in confinement.
