"Protein purification is a common process in many protein-oriented labs. In my picture I wanted to show a final stage of this process, i.e. purified protein dripping down from a purifier. I used a 3D-printed model of a sodium/potassium pump to visualize this concept. I used a syringe and AKTA system connectors to control the size and position of a water drop, and I placed the protein model directly behind the drop. The result was refraction of the model in the drop, looking as if it was contained within the drop. I used a macro lens to capture the picture, and the background was the actual out-of-focus protein model."
