Original title:
Polyvinylpyrrolidone coating for nanodiamond stabilization in saline solution and silver nanoparticle decoration
Authors: Kolářová, Kateřina ; Miliaieva, Daria ; Stehlík, Štěpán
Document type: Papers
Conference/Event: International Conference NANOCON 2020 /12./, Brno (CZ), 20201021

Abstract: This work presents use of polyvinylpyrrolidone (PVP) for multipurpose coating of oxidized high-pressure high-temperature and detonation nanodiamonds. This simple way of nanodiamonds surface modification aims to improve their colloidal stability in biological environments and reduce their proneness to agglomeration. PVP immobilized on nanodiamond surface also provides for nanodiamond-supported AgNPs preparation by in situ synthesis using AgNO3 as a metallic nanoparticles precursor. Dynamic light scattering (DLS) and UV-vis spectroscopy were used for evaluation of nanoparticles size distribution and dispersibility in water and after exposition of nanoparticles in saline solution. Images acquired by scanning electron microscopy and transmission electron microscope validate the possibility of binding ~ 10 nm AgNPs to nanodiamonds surface.
