Nanoparticles are particles with diameters between 1 to 100 nm in size. Similarly, nanosheets are layered two-dimensional nanostructures with thickness ranging from 1 to 100 nm. These layered materials are defined as solids with strong in-plane chemical bonds and weak out-of-plane van der Waals bonds. Both nanosheets and nanoparticles have properties completely different from their bulk precursors. They represent a diverse and largely untapped source of nanosystems with exotic electronic, electrochemical and photonic properties. Additionally, they have high specific surface areas which are important properties for electronics such as transistors, sensors, etc. The goal of the study is to investigate the interactions of emerging 2D materials and model membranes and living organisms in the environment. This presentation focuses on InSe, a 2D material with potential use in optoelectronic applications. The presentation will describe the synthesis and characterization of InSe 2D materials using a recently developed semi bottom up synthesis method. This method, which was recently reported by Motolo and co-workers from the University of the Witwatersrand, South Africa, enables us to produce InSe 2D nanosheets with greater control of flake size, thickness and morphology compared to InSe nanosheets that are formed using mechanical or chemical exfoliation methods. Experiments to determine the impact of InSe 2D materials with varying size, thickness and morphology on zebrafish embryo development are on-going.
