Morphological, optical and anticancer potential of octadecylamine capped palladium sulfide nanoparticles

We report the influence of thermolysis time on the morphological, optical, and anticancer properties of palladium sulfide (PdS) nanoparticles. Powder X-ray diffraction of the as-prepared palladium sulfide nanoparticles confirmed tetragonal-PdS crystalline phase irrespective of thermolysis time. Transmission electron microscopy (TEM) micrographs showed spherically shaped palladium sulfide nanoparticles with particle size in the range 3.00-5.10 nm with optical band gaps of 4.61 for Pd51 prepared at 30 mins, 4.52 for PdS2 prepared at 1 h, and 4.35 eV for PdS3 prepared at 2 h. Anticancer potential of the palladium sulfide nanoparticles against HEK293 and HeLa showed PdS1 and PdS3 are potent against HeLa cells with IC 50 values of 6.25 and 5.71 mu g/mu L.

Automated summary

We investigated the influence of thermolysis time on the morphological, optical, and anticancer properties of palladium sulfide (PdS) nanoparticles. Our results showed that the palladium sulfide nanoparticles maintained a tetragonal crystalline phase regardless of the thermolysis time. The nanoparticles exhibited spherical shapes with particle sizes ranging from 3.00 to 5.10 nm, and the optical band gaps decreased with increasing thermolysis time. Furthermore, the palladium sulfide nanoparticles showed potential anticancer activity against HeLa cells.
