2.Microarray manufacturing The three main manufacturing methods: 。 Contact printing:uses direct contact between the printing implement or the sample contained in the implement and the microarray substrate; Noncontact printing:on-the-fly printing including ink-jet tech.,microsolenoid tech.,and thermal bubble jet dispenser, Semiconductor tech:photolithographic masks and micromirrors.2.Microarray manufacturing The three main manufacturing methods: • Contact printing:uses direct contact between the printing implement or the sample contained in the implement and the microarray substrate; • Noncontact printing:on-the-fly printing including ink-jet tech.,microsolenoid tech.,and thermal bubble jet dispenser; • Semiconductor tech: photolithographic masks and micromirrors
