Researchers use gold nanorod scattering to identify immune system's 'killer and savior'

Researchers have utilized the scattering of gold nanorods to identify M1 and M2 macrophages. Further development of this technique will lead to a new point of care or a biopsy tool which can predict the stages of manifestation of diseases like cancer, atherosclerosis, and fibrosis just from the simple tissue fluids or blood samples.
