The Predictive Synthesis of Monodisperse and Biocompatible Gold Nanoparticles.

The predictive bottom-up synthesis of monodisperse and biocompatible gold nanoparticles using seed-mediated growth procedures is limited by a lack of mathematical models relating reaction components to the final nanoparticle diameter. In this study, we used unique quantitative analytical methods at the single-nanoparticle level to identify the mathematical relationship between the moles of precursor ionic gold and the moles of nanoparticle seeds to synthesize monodisperse gold nanoparticles within ~5% of the target diameter in the ~10 to 120 nm size range. We investigated two commonly used gold nanoparticle syntheses, i.

Toward the Scalable, Rapid, Reproducible, and Cost-Effective Synthesis of Personalized Nanomedicines at the Point of Care.

Organic nanoparticles are used in nanomedicine, including for cancer treatment and some types of COVID-19 vaccines. Here, we demonstrate the scalable, rapid, reproducible, and cost-effective synthesis of three model organic nanoparticle formulations relevant to nanomedicine applications. We employed a custom-made, low-cost fluid mixer device constructed from a commercially available three-dimensional printer.
