      abstract     = {Silver nanoparticles are often employed in medical devices
                      and consumer products due to their antibacterial action. For
                      this, reliable syntheses with quantitative yield are
                      required. Uniform spherical silver nanoparticles with a
                      diameter of about 180 nm were synthesized by carrying out
                      the polyol synthesis in a microwave. Silver nitrate was
                      dissolved in ethylene glycol and poly(N-vinyl pyrrolidone)
                      (PVP) was added as capping agent. The particles were
                      characterized by SEM, HRTEM, XRD, and DLS. The results are
                      compared with the classical method where silver nitrate is
                      reduced by glucose in aqueous solution, heated with an
                      oil-bath. The microwave-assisted synthesis leads to an
                      almost quantitative yield of uniform silver nanoparticles
                      after 20 min reaction time and gives exclusively spherical
                      particles without other shapes like triangles, rods or
                      prisms. Diethylene glycol as solvent gave a more homogeneous
                      particle size distribution than ethylene glycol. For both
                      kinds of particles, dissolution in ultrapure water was
                      examined over a period of 29 days in the presence of oxygen.
                      The dissolution was comparable in both cases (about $50\%$
                      after 4 weeks), indicating the same antibacterial action for
                      particles from the microwave and from the glucose
                      synthesis.},
