262: One pot route to raspberry like silver nanoparticle

Abstract: Hydrosilanes are versatile reagents used in the production of metallic nanoparticles. Previous research in our lab explored long alkyl chain silanes to synthesize metal core nanoparticles1. The chain silanes provided excellent reactivity and stability without compromising the nanoparticle2. For this investigation, we will be utilizing a cyclic hyrosilanes as reducing and stabilizing agents. We will present a one-pot strategy to create a nano-raspberries-like structure arising from utilization of cyclic silanes as stabilizing agents. We have found that the advantage of using silanes is the tunability of alternating the metal nanoparticle surface for catalysis enhancement and additional substrate attachments. This modification can alter its functionality and application to be used in various applications such as catalysis and drug delivery1. This research demonstrates a one-pot inert atmosphere synthesis using two cyclic silanes: D4H, a cyclic substituted siloxane and D4N, a cyclic substituted silane. We explored variations of cyclic silanes to metal salt ratio and the impact it has on the silver nanoparticle morphology and size range3. Resulting products were monitored and characterized via FTIR, UV-Vis and TEM.
