Mesoporous thin films on graphene FETs: Nanofiltered, amplified and extended field-effect sensing
(Royal Society of Chemistry, 2021-12)
The ionic screening and the response of non-specific molecules are great challenges of biosensors based on field-effect transistors (FETs). In this work, we report the construction of graphene based transistors modified ...
Mesoporous ZnS thin films prepared by a nanocasting route
(American Chemical Society, 2012-05)
Mesoporous metal chalcogenides (e.g., ZnS, CuS, and derived mixed sulfide or selenides) show an extremely high potential in technological areas like catalysis, sensors, environmental protection, and photovoltaics. Although ...
Gold semicontinuous thin-film-coated mesoporous TiO2 for SERS substrates
(Springer Nature, 2020-10-10)
In this work, the preparation and thermal evolution of sputtered semicontinuous gold thin films obtained over ordered mesoporous TiO2 films are presented. The controlled surface topography of the ordered mesoporous TiO2 ...
Au Nanoparticles-Mesoporous TiO2 Thin Films Composites as SERS Sensors: A Systematic Performance Analysis
