This strategy can contribute to the development of synthetic receptors to be coupled to biosensor transducers, avoiding the issues associated with proteins such as low stability under different pH and temperature conditions and high production cost. The resulting data of this work indicate a strong interaction between the pesticide dichlorvos and the hexapeptide (NH3+-Glu-His-Gly-Gly-Pro-Ser-COO-) with a binding constant of 4.10 x 10(5) M-1 and the formation of an adduct by covalent binding on the serine residue from the hexapeptide.273-279engArtigo10.1039/c3an01498cWOS:000327548400035Acesso restrito1923726000036625
