Guanine and poly(methyl methacrylate) (PMMA) layers 60 nm thick were fabricated by physical vapor deposition and spin-coating, respectively, for potential application as bio-based field-effect transistors. A few layers of graphene on a variety of non-flexible and flexible supports were used as substrates for the guanine and PMMA layers. The interactions between these layers and graphene were studied...
This paper compares the effect of doped and un-doped biopolymers when the polymers are used as the sensing layer in a resonant chemical sensor. In addition to biopolymers, other polymers were doped as well for reference. The biopolymers used in this study were DNA-CTMA and Silk. The regular polymers used in this study were PMMA and Nafion. PMMA was doped with the metals nickel and iron. DNA-CTMA was...
