The characteristic vibrational spectroscopic fingerprint of Raman reporter molecules adsorbed on noble metal nanoparticles is employed for the identification target proteins by corresponding surface-enhanced scattering (SERS) nanotag-labeled antibodies. Here, we present modular synthesis thiolated polyenes with two to five C═C double bonds introduced via stepwise Wittig reactions. experimental characterization their electronic and properties complemented density functional theory...
A combined atomic force microscope (AFM) and scanning near-field optical (SNOM) has been constructed to obtain images under liquids. In this AFM-SNOM an inverted ac mode configuration is used where the AFM cantilever driven by exciting acoustic modes of liquid cell. Optical latex spheres on a have obtained perfluorononane, butanol, water with lateral resolution 100 nm. Fluorescence perfluorononane. The ability image liquids opens up wide range applications near field microscopy in chemistry biology.
A detailed study of the adsorption structure self-assembled monolayers 4-nitrothiophenol on Au(111) surface was performed from a theoretical perspective via first-principles density functional theory calculations and experimentally by Raman vibrational sum frequency spectroscopy (vSFS) with an emphasis molecular orientation. Simulations—including explicit van der Waals (vdW) description—for different adsorbate structures, namely, for (3×3), (2 × 2), (3 3) unit cells, reveal significant...

Abstract Conventional scanning electron microscopy permits the use of cryogenic techniques, which has led to examination ice-containing samples (eg ice cream) at temperatures -80°C and below. At these moderate etching crystals occurs helps identify in surrounding glassy matrix. However, imaging higher - equivalent those most systems are actually utilised is impossible because rapid sublimation. We have set out develop a system will enable us examine -20°C below, corresponding much more...
