Abstract

The present invention relates to a method for the photolithographic synthesis of biochips in which photolabile protective groups of the 2-(2-nitrophenyl)ethyl type are used, whereby the irradiation step that is common in the photolithographic chip synthesis is carried out in the presence of a base, preferably a secondary or uerriary base.
