title: Non-biological selectivity in amino acids polymerization on TiO₂ nanoparticles.
abstract: For the first, time a strong selectivity is evidenced in inorganic peptide synthesis. When an equimolar mixture of Ala and Arg monomers is added to the synthesis medium of TiO₂ nanoparticles from Ti(IV) isopropoxide in benzyl alcohol, the Ala-Arg dipeptide is observed by ¹³C NMR in the resulting solid, at the exclusion of other dipeptides or higher peptides.
