Peptides are small yet versatile building blocks of biomaterials. This Comment highlights recent progress in the design of liquid-like microdroplets, or coacervates, based on peptides and produced through liquid–liquid phase separation. This emerging platform holds promise as efficacious delivery vehicles for multi-purpose biomedical applications.

Despite concrete being the most prominent building material of the twentieth century, the cultural heritage relevance of concrete buildings and the importance of their preservation is not widely recognized. The European Union project InnovaConcrete’s purpose is to develop nanotechnology-based treatments for concrete preservation and to increase citizen awareness around the importance of concrete-based heritage.
