This study introduces a new high-throughput method for fabricating nanoparticle clusters using DNA-encoded particles on a solid support. The technique yields high quantities of well-defined dimer clusters and Janus nanoparticles with improved efficiency and control.

Area of Science:

  • Nanotechnology
  • Materials Science
  • Supramolecular Chemistry

Background:

  • Self-assembly of nanoscale objects into superstructures and clusters (artificial molecules) is crucial for exploiting collective effects.
  • Biomolecular linkers facilitate nanoparticle cluster construction, but conventional methods suffer from low yields and poor control over product distribution.
  • Challenges include producing homogeneous populations of desired nanoclusters and isomers.

Purpose of the Study:

  • To develop a novel, high-throughput method for designing and fabricating well-defined nanoclusters.
  • To overcome limitations of conventional solution-based assembly methods regarding yield and product homogeneity.
  • To enable precise control over the size and composition of assembled nanostructures.

Main Methods:
