Scale-up Issues for Densely Distributed Analytical Devices 

Obviously, scale up and cost are reciprocally related, and while relatively small-scale deployment for research purposes is possible at current costs (dozens of devices), unit costs must be driven down by orders of magnitude before large scale deployment of devices is feasible. However, the vision from the engineering community is that everything that costs over 25 except food will be connected to the Internet [15]. To quote Kris Pister, from UC Berkeley, by 2010, RF circuits capable of trans- 

We have looked in detail at the analysis of nutrients in natural water, as this is of considerable interest globally, in terms of the overall effect on water quality, and in particular, the prevention of algal blooms which have become an all-too familiar problem in many countries. Bearing in mind the need for inexpensive components and the requirement of low-power operation, we have focused on colorimetric detection using LED/photodiode detection in a microfluidic manifold as a generic
