Soft matter and nanomaterials are two largely overlapping notions that greatly revolutionised materials science in the last decades. Here one of the key concepts is self-assembly, which leads to the appearance of structural features on the scales ranging from a nanometer to microns. In this lecture, I shall mainly focus on synchrotron studies of the self-assembly of nanoparticles, also known as colloids. After a short general introduction into the topic, I shall discuss the self-assembly of magnetic and non-magnetic cubic colloids with rounded edges [1,2]. In-situ studies of the self-organisation of semiconductor quantum dots at a liquid interface [3,4] will be illustrated. I shall describe our recent time-resolved study of the formation of microtubes [5,6], which we use as templates for the fabrication of chiral colloids [7,8]. Finally, new opportunities that can be provided by the EBS upgrade of the ESRF will be briefly discussed.

The ESRF is organising a series of LIVE online seminars on the latest ESRF research. Our scientists will show examples of recent results of experiments carried out at the ESRF and will present what science EBS, the new Extremely Brilliant Source, will enable.

Funding: The organisation of this online seminar series is supported by STREAMLINE, a European project funded by the European Union's Horizon 2020 research and innovation programme under grant agreement No 870313.
