Biochips relate to a number of technologies that involve the merging of semiconductor and biological sciences. The most common form is based on an array of molecular sensors arranged on a small surface _ typically referred to as “lab-on-chip.” The underlying mechanism utilizes microfluidic micro-electromechanical systems (MEMS) technology. These devices are used to analyze biological elements such as DNA, ribonucleic acid and proteins, in addition to certain chemicals.
