The 2018 MicroTAS conference (the 22nd International Conference of Miniaturized Systems for Chemistry and Life Sciences) took us to Kaohsiung, Taiwan, for an inspiring mix of science and culture. The Art in Science competition, sponsored by Lab on a Chip and the National Institute of Standards and Technology, was again a highlight to the meeting, with a collection of 15 excellent images representing the microworld. We were very pleased to have entries in this years contest cover a broad range of subjects and styles, from abstract, single objects to complex structural detail. And it was a great pleasure to view images and to consider the great breadth of applications that the microfluidics community covers. The committee thanks everyone that submitted workwe had a difficult time choosing among the top submissions.
