Yes it is, owing to their physiochemical properties it is attracted in medicinal and pharmaceutical research and there are several studies are extensively reported. These candidates have been studied for their application in different cancer treatments which include, colon cancer, head and neck cancer, solid tumors etc. It also plays a vital role in the drug delivery system and it act as a carrier molecule for different anticancer drugs (doxorubicin, paclitaxel, camptothecin, etc) for the treatment of different cancers.

Its interesting question, I think instead of Gold nano particles, its better if you choose Gold Nano clusters, and then choose your drug molecules according to the nano-cluster size. Following paper will be helpful for you.

There are many publications showing the use of various nano forms of gold e.g as above: Gold nano particles as well as Gold Nano clusters
