The amount of data that is generated globally is increasing exponentially. This data is currently stored on silicon-based chips, which is a process that requires a lot of energy. The Molecular Nanotechnology group of Prof. Dr. Roeland Nolte is exploring alternative methods of writing and storing data, namely as molecular “zeros” and “ones” on a polymer chain with the help of molecular machines. During his Ph.D. studies, Jeroen Bruekers has worked on improving the communication mechanisms within these machines. It is expected that as a result of this these machines can be developed further in the near future, i.e. in such a way that they can store large amounts of data on polymer molecules in an energy-efficient way.
