biomedical applications of superparamagnetic iron oxide nanoparticles (spions) requiring precise control over their physical and magnetic properties, and proper surface treatment. here we report a practical and effective electrochemical strategy for preparation of the polymer coated spions. in this strategy, in situ polymer coating on the surface of spions was achieved through electrodeposition...

ytical device that combines certain biological and physical elements. Several types of transducers are used for elements, such as optical, electrochemical, thermic, or gravimetric. Nowadays, electrochemical have become widely the application biomedical sensors. Electrochemical measurement devices called screen-printed electrodes (SPEs) created by printing several ink on a ceramic plastic substr...

Steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. Consequently, Electrochemical Impedance Spectroscopy (EIS) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect ...

Lactate measurement is vital in clinical diagnostics especially among trauma and sepsis patients. In recent years, it has been shown that saliva samples are an excellent applicable alternative for non-invasive measurement of lactate. In this study, we describe a method for the determination of lactate concentration in saliva samples by using a simple and low-cost cotton fabric-based electrochem...
