5. Labs on a chip
It's just a short step from DNA, protein, sugar or cell biochips to lab-on-chip. The concept of lab-on-chip emerged in the early 1990s, at the same time as DNA chips. These systems integrate all stages of biological analysis, from sample recovery and preparation (cell separation, DNA extraction, PCR, gel migration, labeling, etc.) to signal detection and results (figure

Designed to meet the ever-increasing need for fast, low-cost, automated analysis, lab-on-a-chip systems take miniaturization to new heights. Being mobile, they bring the analysis site closer to the sampling site. This saves time and money.
However, laboratories-on-a-chip are still complex to manufacture....
