Patterning bacteria has been of recent interest for the purpose of providing infrastructure for biotech devices. Receding contact lines can leave behind complex and as yet not fully understood patterns of colloidal particles. We report on investigations into bacterial deposition from sessile drops. Sessile drops containing 4 µL of washed bacterial solution (Pseudomonas Aeruginosa PA01) were dried under continuous air flow and elements of the pattern left behind were analyzed. The coffee ring stains left behind by the drying drops were asymmetric with the widest portion being oriented up wind. Factors influencing the thickness of the up stream ring are reported.
