Biosensors Based on Biological Nanostructures

摘要: The term biomaterials is attributed to the materials employed medical applications, such as ceramic implants and biopolymer scaffolds, well a variety of composites (Hauser e Zhang, 2010). In recent decades, researchers distinct subjects have gathered efforts in developing new for applications various branches medicine. With advent molecular biology biotechnology, knowing that many these are not specific studies been directed towards biological biomimetic preparation (Sanchez, Arribart et al., 2005; He, Duan 2008; Aizenberg Fratzl, 2009). this class materials, peptide compounds appear promising candidates building blocks due their easy physical chemical stability (Cheng, Zhu 2007). Thus, we can propose different sequences from selforganization obtain structures with geometries (spherical, cylindrical, conical) even nanotubes and/or nanofibers (Hirata, Fujimura 2007) obtained. Peptide nanomaterials form supramolecular which interconnected by intermolecular interactions van der Waals forces, electrostatic, hydrophobic hydrogen bonds, among others 2007; Colombo, Soto Due characteristics, crystal engineering architectures has rapidly expanded years, mainly possibility interactions, structural diversity potential Cheng, This possible planning construction architectures, allow design functional will display some sort ownership technological interest nanostructures obtained biomolecules attractive biocompatibility, ability recognition ease modification, important factors on interest. functionalization greatly
