biochip

(bī′ō-chĭp′)
n.
1. An array of miniaturized chemical or biological test sites that is arranged on a substrate so that many tests can be performed simultaneously and that is used to sequence genes, analyze proteins, and identify toxins.
2. A computer chip made from organic molecules rather than semiconductors.

biochip

A microscale system for bioanalysis based on integrated circuit technology.
 
Examples
Molecular microarrays—gene chips, protein chips, small molecule chips; microfluidics systems—lab-on-a-chip; fibre-optic-based arrays.
