Article Synopsis
- Researchers captured tiny oil droplets using a polymer brush made from a hydrophilic aldehyde-functional material.
- The brush was created through a specific polymerization process and modified to add aldehyde groups.
- The study shows that these nanosized droplets can bind to the polymer brush through chemical bonds, which can be adjusted by altering the pH of the solution, providing insights into oil droplet behavior on soft surfaces.
X-ray photoelectron spectroscopy (XPS) depth-profiling with an argon gas cluster ion source (GCIS) was used to characterize the spatial distribution of chlorophyll (Chl) within a poly(cysteine methacrylate) (PCysMA) brush grown by surface-initiated atom-transfer radical polymerization (ATRP) from a planar surface. The organization of Chl is controlled by adjusting the brush grafting density and polymerization time. For , the C, N, S elemental composition remains constant throughout the 36 nm brush layer until the underlying gold substrate is approached.

In these pigment-polymer antenna complexes, localised surface plasmon resonances on gold nanostructures are strongly coupled to Chl excitons, yielding hybrid light-matter states (plexcitons) that are manifested in splitting of the plasmon band. Modelling of the extinction spectra of these systems using a simple coupled oscillator model indicates that their coupling energies are up to twice as large as those measured for LHCs from plants and bacteria.
