Peptoid-Directed Assembly of CdSe Nanoparticles
December 26, 2020
Used components that are tunable at an atomic-level to create a self-assembling hybrid material that is generalizable in composition and structure.
Significance and Impact
This work identifies design parameters to create compatible and stable hybrid assemblies between peptoids and semiconducting nanoparticles.
CdSe nanoparticles were shown to assemble onto peptoid nanostructures with variability both in the peptoid structure (tube or sheet) and size of the CdSe.
Changing the amount of maleimide introduced during peptoid self-assembly allowed control over number of particles bound to a given peptoid sheet.
The binding mechanism between the peptoid and CdSe was investigated using ¹H NMR to determine importance of functional groups both on the QDs and peptoids
Maleimide-containing peptoid tubes and sheets used to assemble CdSe QDs at varying densities depending on maleimide concentration.
