Alkyne-Functionalized Superstable Graphitic Silver Nanoparticles for Raman Imaging
Noble metals, especially gold, have been widely used in plasmon resonance applications. Although silver has a larger optical cross section and lower cost than gold, it has attracted much less attention because of its easy corrosion, thereby degrading plasmonic signals and limiting its applications. To circumvent this problem, we report the facile synthesis of superstable AgCu@graphene (ACG) nan...
متن کاملCarbon-bonded silver nanoparticles: alkyne-functionalized ligands for SERS imaging of mammalian cells.
Silver nanoparticles bonded to terminal alkynes form stable particles in aqueous solution, produce strong SERS signals for molecular imaging that arise from the carbon-metal bond, and expand the scope of molecules that can be used to stably functionalize plasmonic particles for mammalian cell imaging applications. β-Lactams represent a class of biologically important molecules that can be adapt...
متن کاملAlkyne-tag Raman imaging for visualization of small molecules
Raman microscopy has been used for visualizing molecular distribution and dynamics in a living cell [1, 2]. Recently, we have proposed to use alkyne as a tag for Raman imaging of small molecule incorporated into biological samples [3]. Alkyne shows a characteristic peak at Raman silent region (~2050-2300cm) and is free from interference with Raman signal of endogenous biomolecules. Furthermore,...
متن کاملDetermination of ferric ions using surface-enhanced Raman scattering based on desferrioxamine-functionalized silver nanoparticles.
A simple, robust and reproducible spectroscopic method based on surface-enhanced Raman scattering with nanomolar sensitivity has been developed for selective iron(III) determination in aqueous solutions.
متن کاملPolyhexamethylene biguanide functionalized cationic silver nanoparticles for enhanced antimicrobial activity
Polyhexamethylene biguanide (PHMB), a broad spectrum disinfectant against many pathogens, was used as a stabilizing ligand for the synthesis of fairly uniform silver nanoparticles. The particles formed were characterized using UV-visible spectroscopy, FTIR, dynamic light scattering, electrophoretic mobility, and TEM to measure their morphology and surface chemistry. PHMB-functionalized silver n...
