One example is the polymerase chain reaction (PCR), a standard technique which employs enzymes to churn out millions of copies of a DNA sequence and involves cycles of gentle heating and cooling.

ECONOMIST: Acoustic microfluidics

The polymerase chain reaction (PCR) is a scientific technique in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.
