A key challenge in the development of electronic biodevices is to improve the efficiency of long-range charge transfer. Recent results hint at the possibility of achieving this goal by manufacturing novel materials which combine nanoparticles with biological samples showing notable gold nanoparticles-induced enhancement of the electron transfer rates. this interesting result added new facets in nanobioelectronics, although the enhancement mechanism is not yet completely understood.Our goal is to contribute to the elucidation of such mechanism and to optimize these devices in terms of Raman and electron transfer enhancement for biophysical applications as well as for the rational design of nanobiodevices.
