Enzyme screening technology has undergone massive developments in recent years, particularly in the area of high-throughput screening and microarray methods. Screening consists of testing each sample of a sample library individually for the targeted reaction. This requires enzyme assays that accurately test relevant parameters of the reaction, such as catalytic turnover with a given substrate and selectivity parameters such as enantio- and regioselectivity. Enzyme assays also play an important role outside of enzyme screening, in particular for drug screening, medical diagnostics, and in the area of cellular and tissue imaging.

In the 1990s, methods for high-throughput screening of enzyme activities were perceived as a critical bottleneck. As illustrated partly in this chapter, a large repertoire of efficient screening strategies are available today that allow testing of almost any reaction with high-throughput.
