Plasmonic particles like gold nanorods have aroused interest as contrast agents and labels for applications in biomedical optics and photonic sensing.
Here, we review our recent work on complementary use cases of gold nanorods: A concept of cellular vehiculation with tumor-tropic cells, such as immune system cells or stem cells for efficient delivery to the tumor microenvironment; Ways to improve the biosensors of the types in use to detect COVID-19, and in particular, to make the so-called molecular tests much faster with plasmonic PCR (Polymerase Chain Reaction), and the rapid antigen tests much more sensitive by multiplexing and machine learning.
