“…The development of a reliable chemical method for patterning and recognizing molecular inks could impact areas such as localization of biomolecules, directing the growth of cells, , self-assembling nano- and microelectronic devices, , and developing microcontrolled wettability . These patterning inks are a diverse class of materials including small organic molecules (e.g., octyltrimethoxysilane, octadecanethiol), polymers (e.g., poly(methyl methacrylate), polystyrene), and even metallic salts (e.g., GaCl 3 , In(NO 3 ) 3 ) . Peptides are robust biorecognition molecules that can be chemically engineered to bind specific targets and have broad chemical diversity (acidity, hydrophobicity, etc.)…”
