Research output: Contribution to journalArticlepeer-review


A simple and effective way to make DNA patchy particles is reported. A small patch of DNA strands is "stamped" from a gold surface onto colloidal particles of different sizes by streptavidin-biotin bonds. These DNA patchy particles provide direction-selective and thermoreversible interactions, and hence can lead to unique assembly protocols and structures controlled by temperature.
