How does confinement alter the transport properties of colloidal particles, the functionalities of molecular machines and in general the mechanisms of energy-transfer and energy-conversion at small scales? This question, fundamental for the modelling of soft-matter systems and biological systems, is attracting the interest of many researchers in the field. In a basic model proposed, the confinement effects are considered through an entropic potential. It has been shown that transport through entropic barriers or entropic transport exhibits peculiar characteristics very different from those observed when activation takes place through energetic barriers. In this talk, I will review recent progresses in the study of entropic transport and its applications to soft-matter and biological systems. I will show that the confinement plays a very important role in the mechanisms of energy-conversion at the nanoscale, in particular in the functionality of molecular machines.
