In-Depth Information
eliminate the need for sample collection, preparation, and laboratory analysis. Many of the
new products that incorporate biosensors must be small and robust, should operate
quickly, and have low power requirements to be able to deliver the analytical information
in a simple, inexpensive manner. The development of futuristic biosensors and sensory
systems requires careful attention to both the recognition layer and physical transducer,
and the coupling of these recognition transduction elements through the control of surface
chemistry. Recent advances in understanding biological materials, the development of
new manufacturing processes, and the exploitation of information or computing technol-
ogy as described in this volume will all work toward achieving this goal.
Finally, it is also important to understand the constraints and limitations of the design
approach taken. As scientists and engineers, we should always question our motivations
and ask ourselves why we choose a particular direction of study to solve a problem.
Mimicking biological sensory systems may lead to innovative solutions but may also be a
pathway riddled by pitfalls.
