This article explores an ensemble of technical objects and biological objects in bio-art and proposes aesthetic values that the ensemble reveals. French philosopher Gilbert Simondon considered technical objects carefully in the 1950s. In his study, he was alert to an assimilation of technical objects to biological objects. In our time, the development of molecular biology and genetic engineering offers evidence that technical objects are closely linked to biological objects. The process of concretizing technical objects and biological objects is latent in works of bio-art, which therefore can realize aesthetic potentials that technical objects and biological objects imply.
