Robust Assembling System for Photosynthesis-Based Microbiosensors

A micro-biosensor is a complex device and, at micro-nano scale, the stability of multiple phenomena interactions depends critically on a multitude of factors. To build a robust micro-biosensor, a special attention for reliability issues must be paid. In a previous work, solutions for building an amperometric micro-biosensor based on the inhibition of the photosynthesis process at cyanobacteria, are introduced. In this paper, the improvement on reliability criteria of the innovative assembling system of the micro-biosensor is presented. First, the technological conditions for performing the mounting processes where established following the directions resulting by the "design for reliability" approach. The devices where tested by accelerating the relaxing of the internal stresses. In a second stage, the technological conditions where optimised, based on the experimental reliability results.
