By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Bacteriophages are presented in a new report. According to news reporting originating in Cambridge, Massachusetts, by NewsRx journalists, research stated, "By genetically encoding affinity for inorganic materials into the capsid proteins of the M13 bacteriophage, the virus can act as a template for the synthesis of nanomaterial composites for use in various device applications. Herein, the M13 bacteriophage is employed to build a multifunctional and three-dimensional scaffold capable of improving both electron collection and light harvesting in dye-sensitized solar cells (DSSCs)., This has been accomplished by binding gold nanoparticles (AuNPs) to the virus, proteins and encapsulating the AuNP-virus Complexes in TiO2 to produce a plasmon-enhanced and nanowire (NW)-based photoanode."
The news reporters obtained a quote from the research from the Massachusetts Institute of Technology, "The NW morphology exhibits an improved electron diffusion length compared to traditional nanoparticle-based DSSCs, and the AuNPs increase the light absorption of the dye molecules through the phenomenon of localized surface, plasmon resonance. Consequently, we report a virus-templated and plasmon-enhanced DSSC with an efficiency of 846%, which is achieved through optimizing both the NW morphology and the concentration of AuNPs loaded into the solar cells."
According to the news reporters, the research concluded: "In addition, we propose a theoretical model that predicts the experimentally observed trends of plasmon enhancement."
