Self-assembling peptides have emerged as a novel generation of materials that can be designed to attain one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) nanostructures with different potential applications, such as bioimaging, tissue engineering, controlled drug delivery and as detectors and transducers in biosensors. The peptide compounds represent the most versatile molecular building blocks, due to rich chemical diversity and an inherent ability to effectively interface with biological systems. Many reports are available on the use of cyclic peptides, amphiphiles, bolaamphiphiles, ionic peptides, surfactant-like peptides and hydrophobic dipeptides for nanostructure generation. The functionalization of these nanomaterials with nanoparticles of transition metals, polymers, photoluminescent compounds, among others, has increased the sphere of applications of the biological nanostructures. This talk focuses on the design of biological materials as functional electrode surfaces and the immobilization of enzyme molecules and biomimetic systems for potential applications in biosensors and molecular electronic devices.
