Abstract
Micron sized latex particles with single stranded DNA grafted to the surface have been used as a model system to study DNA mediated interactions. A new approach to tuning the interactions between particles has been proposed. This approach allows a gradual change of the assembly rate for fixed physical conditions of a solution by mixing of hybridizing "linker" and non-hybridizing "neutral" DNA strands. The particle assembly kinetics and the aggregate morphology have been investigated for a range of ionic strengths and "linker"/"neutral" DNA ratios. The conditions for various assembly kinetics have been identified.
