BioArt is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy, and biotechnology the artworks are produced in laboratories, galleries, or artists' studios. The scope of BioArt is a range considered by some artists to be strictly limited to "living forms", while other artists include art that uses the imagery of contemporary medicine and biological research, or require that it address a controversy or blind spot posed by the very character of the life sciences.

Microbial art, agar art, or germ art is artwork created by culturing microorganisms in certain patterns. The microbes used can be bacteria, yeast, fungi, or less commonly, protists. The microbes can be chosen for their natural colours or engineered to express fluorescent proteins and viewed under ultraviolet light to make them fluoresce in colour.
