The Role of Endogenous Metal Nanoparticles in Biological Systems

open access: yesBiomolecules, 2021
The blood and tissues of vertebrate animals and mammals contain small endogenous metal nanoparticles. These nanoparticles were observed to be composed of individual atoms of iron, copper, zinc, silver, gold, platinum, and other metals.

Divalent Metal Nanoparticles [PDF]

open access: yesScience, 2007
Nanoparticles can be used as the building blocks for materials such as supracrystals or ionic liquids. However, they lack the ability to bond along specific directions as atoms and molecules do. We report a simple method to place target molecules specifically at two diametrically opposed positions in the molecular coating of metal nanoparticles.

Metallic nanoparticles meet metadynamics [PDF]

open access: yesThe Journal of Chemical Physics, 2015
Metadynamics coupled with classical molecular dynamics has been successfully applied to sample the configuration space of metallic and bimetallic nanoclusters. We implement a new set of collective variables related to the pair distance distribution function of the nanoparticle to achieve an exhaustive isomer sampling. As paradigmatic examples, we apply
