Enhanced Self-Organized Dewetting of Ultrathin Polymer Blend Film for Large-Area Fabrication of SERS Substrate

Scientific Reports (2016)

Huanhuan Zhang Lin Xu Yabo Xu Gang Huang Xueyu Zhao

Abstract We study the enhanced dewetting of ultrathin Polystyrene (PS)/Poly (methyl methacrylate) (PMMA) blend films in a mixed solution, and reveal the dewetting can act as a simple and effective method to fabricate large-area surface-enhanced Raman scattering (SERS) substrate. A bilayer structure consisting of under PMMA layer and upper PS layer forms due to vertical phase separation of immiscible PS/PMMA during the spin-coating process. The thicker layer of the bilayer structure dominates the dewetting structures of PS/PMMA blend films. The diameter and diameter distribution of droplets, and the average separation spacing between the droplets can be precisely controlled via the change of blend ratio and film thickness. The dewetting structure of 8 nm PS/PMMA (1:1 wt%) blend film is proved to successfully fabricate large-area (3.5 cm × 3.5 cm) universal SERS substrate via deposited a silver layer on the dewetting structure. The SERS substrate shows good SERS-signal reproducibility ( RSD < 7.2%) and high enhancement factor (2.5 × 10 7 ). The enhanced dewetting of polymer blend films broadens the application of dewetting of polymer films, especially in the nanotechnology, and may open a new approach for the fabrication of large-area SERS substrate to promote the application of SERS substrate in the rapid sensitive detection of trace molecules.

Understanding Quantum Plasmonic Enhancement in Nanorod Dimers from Time-Dependent Orbital-Free Density Functional Theory

The Journal of Physical Chemistry C (2022)

Hongping Xiang Jiaxing Zu Hongwei� Jiang Lin Xu Gang Lü

Localized surface plasmon resonances could yield extreme enhancement of local electric fields at surfaces of plasmonic nanostructures. Herein, we have performed quantum mechanical simulations to systematically study plasmonic resonances in sodium (Na) nanorod dimers based on time-dependent orbital-free density functional theory. Several representative geometries, including end-to-end, side-to-side, and right-angle T- and L-shaped dimer arrangements are explored in detail. The optical spectra, tunneling electric current, and electric field enhancement (hot spots) are examined as a function of the size of the nanorods, their relative arrangement, and their gap distance (≤2 nm). Two plasmon resonant modes are identified to be responsible for the observed electric field enhancement. One of them is of quantum nature, arising from quantum tunneling across the gap of the two nanorods. The other mode is of electrostatic nature, originating from the dipolar interaction between the plasmonic oscillations of each nanorod. Among the examined geometries, the end-to-end dimer exhibits the strongest field enhancement, which increases with the aspect ratio and the gap distance. The interplay between electron tunneling across the gap and the spill-out of electrons at the nanorod surfaces is revealed to dominate the modulation of plasmonic resonances and field enhancement in the nanorod dimers.

Cell Compatibility of the Micro-Arc Oxidized Surface of Large Plastic Deformed TA2<i> In Vitro</i>

Materials science forum (2016)

Li Zhu Xiao Jing Xu Ting Zhuo Chen Xiao Ya Niu Lin Xu

The cell toxicity, cell proliferation and cell adhesion behaviors on the micro-arc oxidized surface of the conventional and large plastic deformed pure titanium (TA2) were studied. The results show that all samples have no cell toxicity. The cell proliferation ability on the surface of the large plastic deformed pure titanium (TA2) is better than that of the conventional pure titanium (TA2). The numbers of cells adhered on micro-arc oxidized surface of the large plastic deformed of pure titanium (TA2) are more than that of conventional pure titanium (TA2). And the distribution of the cells and cell morphologies are better than that of the conventional pure titanium (TA2). Results all above show that structure refinement of large deformation of pure titanium (TA2) has more significant improvement on the cell compatibility of the micro-arc oxidized modified films.
