Dopamine molecule line tattoo on the side of the body

Fine line · Other · Black and grey · Photo

A black line drawing of the dopamine molecule sits on smooth skin, showing a benzene ring with two hydroxyl groups and a chain ending in an NH2 amine group. The linework is thin and even, with the lettering set in a clean sans-serif. The tattoo is shown in close view against a plain skin tone, with a strip of teal fabric at the top edge of the frame.

A story inspired by this tattoo · fiction

Ruth drew molecules on everything. Chromatography printouts, the backs of invoices, once the lid of a freezer box in marker so fine I had to read it with a torch. She said a structure was a sentence you could hold in your head if you didn't rush it, and she never rushed. The night the column cracked, she sat on an upturned crate by the fume hood and drew the same six-sided ring again and again while the pump hissed like a kettle nobody wanted to answer.

"Two hydroxyls, see," she said, tapping the paper with her biro. "Two little doors in the ring. Whatever carries a message from one cell to the next has to pass through a shape like that." She drew the tail: two carbons, then a nitrogen with its pair of hydrogens, a small neat ending that looked folded shut on purpose.

I asked her why she never had it inked somewhere, since she loved it so much. She shrugged and said paper was honest because you could rub out a mistake, and skin was just paper that kept score. Then she went back to the column, swapped the cracked fitting with a steady hand, and watched the baseline settle into a line as flat as a ruler.

In the morning the bench was wet with coffee and the printouts were gone. The only thing left was a scrap she'd forgotten, the ring drawn over and over until the paper had torn through at one corner. I folded it into my pocket. Later, in the car park, I copied the shape onto the back of my wrist in biro, two little doors and a tail, and it stayed there until I scrubbed it off in the sink that evening.
