Article
An electrochemical-sensing platform for determination of dopamine (DA) was fabricated using MnO2–polyaniline (MnO2–PANI) composite. The MnO2–PANI composite was prepared through in situ radio-frequency plasma polymerization of aniline monomer over MnO2 under rotating conditions and followed by external iodine doping to boost conductivity of final I2...

In this study, a new lactose biosensor has been developed in which the 3,4-ethylenedioxythiophene/thiophene (EDOT/Th) copolymer is used as a transducer. The EDOT/Th copolymer was deposited on the glassy carbon electrode to be used as the working electrode. In addition to the working electrode, the three-electrode system was used in both the electro...

Lactose content of milk is a basic indicator for the evaluation of milk quality. Various methods are used for the determination of lactose; however, many of these methods are generally time-consuming, labor-intensive and expensive for routine quality control applications. Biosensors offer a cheap, quick, and reliable alternative for lactose determi...
Conference Paper
Carbon nanotubes (CNT) is one of the most investigated materials before the invention of graphene. 1 Due to its unique properties, CNTs have been used in various applications include sensors, solar cells, transistors, etc. 2 However, it makes difficult to make nano-devices based on CNTs at a large scale. For this reason, formation of composite with...
