Nanoparticle film properties significantly impact vapor molecule sorption. Core size and linker chemistry influence sensor response to polar and nonpolar vapors, guiding the design of new chemical sensors.

Area of Science:

  • Materials Science
  • Nanotechnology
  • Chemical Sensing

Background:

  • Nanostructured films offer unique properties for chemical sensing.
  • Core-shell nanoparticles provide tunable interfaces for molecular interactions.

Purpose of the Study:

  • Investigate vapor molecule sorption on nanostructured nanoparticle films.
  • Determine the influence of nanoparticle core size and linker chemistry on sensor response.
  • Correlate electronic resistance and mass loading with vapor sorption.

Main Methods:

  • Utilized core-shell nanoparticles (Au2-nm, Au5-nm) with varying linker molecules (1,9-nonanedithiol, 11-mercaptoundecanoic acid).
  • Employed interdigitated microelectrodes and quartz crystal microbalance transducers.
  • Measured electronic resistance change and mass loading during vapor sorption.
