Special delivery: The “freezing” of activated amino acid derivatives within solid particles enables a laser printer to deliver these “postal packages” to defined locations on a solid support with high resolution. Subsequent parallel coupling is initiated simply by melting a whole layer of 20 different amino acid particles (see schematic representation; Fmoc=9-fluorenylmethoxycarbonyl).
