Multi-material nano3D printer to do extremely miniaturized chemical synthesis in the array format
Our novel multi-material nano3D printer  can be used to synthesize very-high-density peptide arrays, (more) but recently we realized that it can also be used to combinatorial stack nanolayers with embedded educts, e.g. for the synthesis of fluorescent molecules.  Currently, we explore together with our cooperation partners Prof. Stefan Bräse, Dr. Dario Mager, Prof. Jan Korvink, and Prof. Carsten Hopf the extremely miniaturized combinatorial synthesis of many different “light-harvesting-molecules”. One future application might then be the screening for catalysts that use the energy of the Sahara sun to reduce carbon dioxide (Fig. 6). Applications of this type might pave the way for a future green chemistry.
