Description
Gold nanoparticles (AuNPs) are used in experimental cancer treatments and developed in various shapes and sizes to optimize drug delivery, imaging, and photothermal therapy. In this study, small gold nanospheres (20-30 nm), large nanospheres (50-60 nm), nanorods, and nanostars were synthesized and analyzed. Dynamic light scattering, ultraviolet-visible spectroscopy, and transmission electron microscopy were techniques deployed to determine particle size, level of uniformity, particle absorption of light, and overall AuNP morphology. AuNPs shape and size changed which altered their interaction with light. Our results aid in informing AuNP design for future cancer treatments.
