Test tubes and petri dishes feature prominently in Fan’s practice, as the artist often utilizes biological substances such as testosterone, estrogen, and melanin in his sculptures. Fan has worked with a research lab to manufacture and extract these often politically contested materials, detaching them from the context of the body in order to examine their significance. For a series of sculptures entitled Systems, Fan injected testosterone, estrogen, and melanin into organ-like glass-blown globules, which were then precariously hung from forms resembling lattices. In the video work, Mother Is a Woman, Fan used estrogen from his mother’s urine to create a custom beauty cream, asking if qualities like femininity and maternalism usually associated with estrogen could be transferred through a commercial product. Such works question the role that these biological substances have played in constructing binary identity categories and draw upon the artist’s experiences of being racialized and gendered. Ultimately, Fan asks, “How can we be certain that the binary can satisfy us?”
