Electrical properties design strategy

The design of artificial peptide sequences for the preparation of responsive surfaces takes advantage of the wealth of literature and information available on how the sequence of amino acids in a peptide chain affect the overall properties of the peptide (Boyle Woolfson, 2011 Bromley et al., 2008). The two general strategies employed so far are the exploitation of charge effects on the secondary conformation of the peptide and the ability of dipole moments of helical peptides to direct an electric current (Figure 3.5). 

On the other hand, linear and nonlinear responses are evaluated in a strategy of designing new systems with remarkable electric, magnetic, and optical properties. In this second motivation for calculating the polarizabilities and h q)erpolarizabilities, the emphasis is also put on the interpretation and the deduction of structure-property relationships while these investigations are parts of multidisciplinary approaches including synthetic and experimental characterizations.
