Directions of technological progress

Matrix systems - GeneChip Stephen P.A. Fodor, PhD, CEO of Affymetrix In 1989, he joined the Affymax Research Institute in Palo Alto, where he spearheaded the effort to develop high-density arrays of biological compounds. Dr. Fodor and his colleagues were the first to develop and describe microarray technologies and combinatorial chemistry synthesis.

Biochips Acad. Andrei Mirzabekov In late 1980-ties launched a new scientific field – technology of micromatrics-sensors or biochips [Лысов, Ю., Флорентьев В., Хорлин, A., Храпко, K., Шик, В., Мирзабеков, A. Определение нуклеотидной последовательности ДНК гибридизацией с олигонуклеотидами. Новый метод. (1988) Докл. Aкад. Наук СССР, 303, 1508-1511].
