For familiarity and precision, Dunn had taken to using lab supplies in his artwork. He sheepishly admits that he did a bit of an informal exchange with his former lab, trading easily obtainable items for specialized lab supplies of equal monetary value, such as scissors for syringes.

Now that he's no longer working in a lab, getting ahold of the supplies has become a little bit tricky: "You say to the pharmacy, 'Can I get some syringes for my artwork.' They're like 'Yeah, get outta here.'" But the level of precision required in art is nowhere near that for molecular biology--try visualizing 0.2 microliters of fluid--so Dunn is flexible with his equipment these days.
