There is much more to sense there than we can even think of. Although we have super-dupertechnology for chemical analysis, practitioner and the market are literally hungry of biosensors. They should be portable, easy to use, universal, sensitive, and selective, and cheap, really cheap. This is impossible, of course. So we proceed for small approximations, covering a small use case after the other. However, very few of these products reach the market. Why? What are the three most important things to do (IMHO) to design a good sensor that might reach the market in reasonable time?

  1. Collaborate from the beginning with the practitioner. They know their business and they know exactly what they want, so they can help us getting rid of old/uproductive idea and focus on really applicable concepts.
  2. It is OK to work on a focused use case and understanding from the very beginning the limitation of our design. The concept on which our biosensor is based can be really novel, but the application should be boringly effective in a specific scenario.
  3. Be selective. No one needs a baely working biosensor. Focus only on those applications that show immediately good promises.
