A biosensor for the detection of ascorbic acid is developed by preparing a carbon paste electrode (CPE) electrochemically deposited with Prussian blue (PB) and DNA adsorbed on its surface. Cyclic voltammetry (CV) was used to study the electrochemical properties of the biosensor. The successful electro-deposition of PB was confirmed using Raman Spectroscopy. From the results it was concluded that PB...
The decomposition of the pharmaceutical compound enalapril in aqueous solution using non-thermal plasma has been investigated. The plasma was generated in a dielectric barrier discharge reactor (DBD) in coaxial configuration, at the interface between gas (oxygen at atmospheric pressure and room temperature) and the solution which flows as a thin film on the surface of the inner electrode of the plasma...
The current research leverages a nanotechnology enabled sensor platform for highly sensitive detection of pharmaceuticals contaminants in water samples using electrochemical impedance spectroscopy. The sensor surface consists of lithographically patterned gold electrodes and is functionalized with anti-pharmaceutical antibodies. A nanoporous alumina membrane is placed over the sensor surface to achieve...
Electrocatalytic oxidation of indomethacin on a modified multiplewalled carbon nanotubes (MWCNTs) cathode in aqueous solution was studied in this paper. The experiments were carried out to explore the effects of initial concentration, electrolytic voltage, pH, concentration of electrolyte and electrolysis time on removal rate of indomethacin. The results of show that the removal rate reached 78% by...
This paper shows the applications of an automated analytical system based on the sequential injection analysis technique (SIA). Every year, thousands of clinical analyses are made for diagnostic or preventive purposes; due the large amount of samples, automated analytical systems are necessary to provide accurate information quickly. Systems based on the SIA technique have shown a good performance...
An electron synchrotron is the most universally usable type of accelerator, constituting an intensive source of light with unique features. It is used for advanced experiments, thanks to which it is possible to gain unique information on behaviour of matter on molecular and atomic levels. Data provided by synchrotrons are important for the competitiveness of the future industry in the EU. They will...
In this paper we present a method for fast and accurate in-line weighing of hard gelatin capsules based on real-time processing of the capsule capacitance profile resulting from 5000 capacitance measurements per second. First, the effect of the shape and size of the capacitive sensor on the sensitivity and stability of the measurements was investigated in order to optimize the performance of the system...
A novel method named wavelet packet transform based Elman recurrent neural network (WPTERNN) was proposed for simultaneous determination of Co (II), Zn (II) and Cu (II) by combining wavelet packet denoising with Elman recurrent neural network. Wavelet packet representations of signals provided a local time–frequency description, thus in the wavelet packet domain, the quality of the noise removal can...
