What is it about?
Second law of thermodynamics dictates that the free energy of a system will reach its minimum. This phenomenon is seen adsorption process as well where amphiphilic molecules will start reducing the surface free energy of freshly created surface. However, we found that in case of proteins there is a transient increase in surface energy before it starts to decrease.

Why is it important?
This work sheds a new light on the thermodynamics of adsorption process involving proteins. We have demonstrated that the kinetics of adsorption is not straightforward and it is more non-linear at shorter time scales.
