Breast cancer detection using charge sensors coupled to DNA monolayer
(2015-01-01)
We report the development of a label-free biosensors based on DNA hybridization, using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). This study uses DNA sequences based on microRNA related with ...
Label-free Capacitive Diagnostics: Exploiting Local Redox Probe State Occupancy
(Amer Chemical Soc, 2014-03-04)
An electrode surface confined redox group contributes to a substantial potential-dependent interfacial charging that can be sensitively probed and frequency-resolved by impedance-derived capacitance spectroscopy. In utilizing ...
Detection of several carbohydrates using boron-doped diamond electrodes modified with nickel hydroxide nanoparticles
(2015)
In this work the electrooxidations of glucose, galactose, mannose, rhamnose, xylose and arabinose are studied at a nickel hydroxide nanoparticle modified boron-doped diamond electrode and compared to an unmodified electrode. ...
Melanin as an active layer in biosensors
(American Institute of Physics (AIP), 2014-03-01)
The development of pH sensors is of great interest due to its extensive application in several areas such as industrial processes, biochemistry and particularly medical diagnostics. In this study, the pH sensing properties ...
Corrosion behaviour of aluminium syntactic functionally graded composites
(2010)
Syntactic Functionally Graded Metal Matrix Composites (SFGMMC) are a type of composites reinforced by microballoons exhibiting a graded reinforcement distribution. These materials constitute a promising new generation of ...
Electrical and mechanical characterization of a flexible conducting composite
(Springer, 2015-07-01)
Composite films made of poly(vinylidene fluoride) (PVDF) and conducting particles of carbon black (CB) were prepared using a hot press. Using different volume fractions of CB filler, electrical properties of the samples ...
Reduced graphene oxide decorated with AuNPs as a new aptamer-based biosensor for the detection of androgen receptor from prostate cells
(2019-01-01)
Here we described an aptasensor based on graphene oxide (GO) decorated with gold nanoparticles (AuNPs) able to detect the AR released by prostate cells, in order to provide new insights about the relationship between AR ...
Graphene Functionalization and Nanopolymers
(2019-01-01)
This chapter focuses on the functionalization of graphene, mainly in graphene oxide (GO) and reduced graphene oxide (rGO). In this sense the main syntheses for obtaining GO and rGO, as well as their characterizations and ...
The use of nanostructured films in sensing applications
(2013-08-31)
In this chapter, we describe developments on the use of impedance spectroscopy and ultrathin films of different materials in the analysis of liquid samples via weak, non-bonding molecular interactions. Despite the lack of ...
A functionalized renewable carbon-based surface for sensor development
(2021-03-01)
This paper describes the surface modification of glassy carbon (GC) electrodes with a bamboo-based renewable carbon (RC) before and after an acid functionalization procedure with a sulfonitric solution (1:3 HNO3/H2SO4). ...
