Restricted diffusion of guest molecules in polymer thin films on solid substrates as revealed by three-dimensional single-molecule tracking.
نویسندگان
چکیده
3D single-molecule tracking revealed that the translational diffusion of guest dyes in poly(2-hydroxyethyl acrylate) thin films on glass substrates was confined in a horizontal layer at a distance longer than 300-700 nm from the surface of the substrate. This peculiar long-range effect suggests that the interaction between the host polymer and the interface could affect the properties of polymers at a much longer distance than conventionally estimated.

Over the past few years, nano-science and its associated nano-technology have emerged into prominence in research instiutions across the world. They have brought about new scientific and engineering paradigms, allowing for the manipulation of single atoms and molecules, designing and fabricating new materials, atom-by-atom, and devices that operate on significantly reduced time and length sca...
متن کاملDiffusion processes of single fluorescent molecules in a polymer-based thin material with three-dimensional network.
Single-molecule imaging revealed the hierarchical mobility change of guest dyes in a polymer-based thin film under network formation: at the early stage of the reaction, only the translational diffusion was inhibited while keeping the rotational diffusion active, the fraction of translationally immobilized dyes increased with increasing crosslinking, and at the last stage both motions stopped.

In this work, aluminum nitride (AlN) thin films with different thicknesses were deposited on quartz and silicon substrates using single ion beam sputtering technique. The physical and chemical properties of prepared films were investigated by different characterization technique. X-ray diffraction (XRD) spectra revealed that all of the deposited films have an amorphous str...
متن کاملGuest molecule diffusion and conformation influenced by local liquid crystal structure
Optical single molecule investigations are superior to ensemble methods in revealing local structure and dynamics of thin soft matter films. Here we use tailored perylene diimide (PDI) molecules to probe the diffusion of guest molecules in 50 to 200 nm thick films of the liquid crystal 4-n-octyl4’-cyanobiphenyl (8CB) on silicon with either thin native or 100 nm thick thermal oxide. These PDI mo...
متن کاملSingle-molecule tracking of polymer surface diffusion.
The dynamics of polymers adsorbed to a solid surface are important in thin-film formation, adhesion phenomena, and biosensing applications, but they are still poorly understood. Here we present tracking data that follow the dynamics of isolated poly(ethylene glycol) chains adsorbed at a hydrophobic solid-liquid interface. We found that molecules moved on the surface via a continuous-time random...
