Preparation of self-assembled platinum nanoclusters to combat Salmonella typhi infection and inhibit biofilm formation.

In this work, phytoprotein functionalized platinum nanoparticles (PtNCs) were synthesized using the proteins from fresh green spinach leaves. Transmission electron microscopy showed that PtNCs were spherical shape with size ∼5 nm, which self assembled into spherical platinum nanoclustures (PtNCs) with size within the range of 100-250 nm. The presence of elemental platinum was confirmed by EDX analysis.
