Electrochemical DNA biosensor based on conducting polyaniline nanotube array.
Most of the recent developments in ultrasensitive detection of nucleic acid are based on the gold nanoparticles and carbon nanotubes as a medium of signal amplification. Here, we present an ultrasensitive electrochemical nucleic acid biosensor using the conducting polyaniline (PANI) nanotube array as the signal enhancement element. The PANI nanotube array of a highly organized structure was fab...
متن کاملFabrication of a novel glucose biosensor based on a highly electroactive polystyrene/polyaniline/Au nanocomposite.
A novel nanocomposite with a core-shell structure containing polystyrene (PS), polyaniline (PANI), and Au nanoparticles (NPs) was synthesized. The nanocomposite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR). Cyclic voltammetric ex...
متن کاملCholesterol biosensor based on electrochemically prepared polyaniline conducting polymer film in presence of a nonionic surfactant
Cholesterol biosensor has been fabricated by covalently coupling cholesterol oxidase (ChOx) via glutaraldehyde onto electrochemically prepared polyaniline film in presence of TritonX-100 [4-(1,1,3,3-tetramethylbutyl) phenyl polyethylene glycol], a non-ionic surfactant onto indium-tin-oxide (ITO) glass substrate. These ChOx/PANITX-100/ITO bioelectrodes have been characterized using Fourier trans...
متن کاملA novel amperometric biosensor based on gold nanoparticles-mesoporous silica composite for biosensing glucose
We report a novel bienzyme biosensor based on the assembly of the glucose oxidase (GOD) and horseradish peroxidase (HRP) onto the gold nanoparticles encapsulated mesoporous silica SBA-15 composite (AuNPs-SBA-15). Electrochemical behavior of the bienzyme bioconjugates biosensor is studied by cyclic voltammetry and electrochemical impedance spectroscopy. The results indicate that the presence of ...
متن کاملFiber-optic glucose biosensor based on glucose oxidase (GOD) immobilised in a silica gel matrix
In this paper, we report results obtained from a biosensor comprised of a monolithic silica sol–gel entrapping glucose oxidase (GOD) as sensing element coupled to a fibre-optic transducer element. GOD intrinsic fluorescence spectra were analysed in the UV and visible region in presence of different glucose concentrations, and the corresponding calibration curves were obtained. In addition, time...
