In recent years there has been a great effort in biology, chemistry and engineering to pursue the advantages of miniaturization for cheaper better faster sample analysis. So far, the aim has been mainly the speed-up of DNA amplification and detection and other molecular analysis from preprocessed samples. To attain the pervasiveness enjoyed today by electronic devices, a much higher degree of functional integration will be required, for the new goal of sample-to-answer systems. This presentation will discuss the main challenges and unmet needs to seize the opportunities existing for cheap and ubiquitous bioanalytical devices, and how microelectronic technology could play a leading role.
