| Title: | Thermal and aqueous stability improvement of graphene oxide enhanced diphenylalanine nanocomposites | Authors: | Ryan, Kate; Neumayer, Sabine M.; Maraka, Harsha Vardhan R.; Buchete, Nicolae-Viorel; Kholkin, Andrei L.; Rice, James H.; Rodriguez, Brian J. | Permanent link: | http://hdl.handle.net/10197/8512 | Date: | Feb-2017 | Online since: | 2017-05-12T11:58:28Z | Abstract: | Nanocomposites of diphenylalanine (FF) and carbon based materials provide an opportunity to overcome drawbacks associated with using FF micro- and nanostructures in nanobiotechnology applications, in particular, their poor structural stability in liquid solutions. In this study, FF/graphene oxide (GO) composites were found to self-assemble into layered micro- and nanostructures, which exhibited improved thermal and aqueous stability. Dependent on the FF/GO ratio, the solubility of these structures was reduced to 35.65% after 30 min as compared to 92.4% for pure FF samples. Such functional nanocomposites may extend the use of FF structures to, e.g., biosensing, electrochemical, electromechanical or electronic applications. | Funding Details: | European Commission - European Regional Development Fund European Commission - Seventh Framework Programme (FP7) Science Foundation Ireland |
