Abstract:
This paper presents a whole-cell bio-chip system where viable, functioning cells are deposited onto solid surfaces that are a part of a micro-machined system. The development of such novel hybrid functional sensors depends on the cell deposition methods; in this work new approach integrating live bacterial cells on a bio-chip using electrophoretic deposition is presented. The bio-material deposition technique was characterized under various driving potential and chamber configurations. The deposited bio-mass included genetically engineered bacterial cells generating electrochemically active byproduct upon exposure to toxic materials in the aqueous solution. In this paper we present the deposition apparatus and methods, as well as the characterization results, e.g. signal vs. time and induction factor, of such chips and discussing the highlight and problems of the new deposition method.
