Welcome to the Shahrokhian,s Research Group Website. Electrochemical research laboratory, led by Dr. Shahrokhian, is located in the Chemistry Department at Sharif University of Technology, Tehran, Iran. Research in the Electrochemical Laboratory is focused on design, fabrication, development and application of electrochemical sensors in trace analysis of pharmaceutical and biological species and fabrication electrochemical modified electrodes with nanomaterial to study electrochemical phenomena and their application in supercapacitors. Our aim is to design novel modified electrodes for electro analytical determinations with good efficiency and acceptable performance. We believed that creativity, critical thinking, knowledge, and independence as prosperous feature are important for any developing research in our laboratory. Please explore the website to learn more about the research fields and projects in the laboratory and the researcher behind the scenes.

Research Fields

Supercapacitor (SC), also called ultracapacitor or electrochemical capacitor, is a high-capacity capacitor store electrical charge on conducting materials with high-surface-area. Capacitance values of this device may be higher than 1,000 farads at 1.2 volt that bridge the gap between electrolytic capacitors and rechargeable batteries. Supercapacitors are used in applications requiring many rapid charge/discharge cycles rather than long term compact energy storage: within cars, buses, trains, cranes and elevators, where they are used for regenerative braking, short-term energy storage or burst-mode power delivery. Smaller units are used as memory backup for static random-access memory (SRAM).

Biosensor is a device that uses a living organism or biological molecules, to detect the presence of chemicals. This device combines a biological component with a physicochemical detector. The sensitive biological element enzymes, antibodies, nucleic acids and aptamers bind for recognize the target analyte. A common and practical example of a commercial biosensor is the blood glucose biosensor, which uses the enzyme glucose oxidase to break blood glucose down. In doing so it first oxidizes glucose and uses two electrons to reduce the FAD (a component of the enzyme) to FADH2. The resulting current can be related to the concentration of glucose.

The main aim of the pharmaceutical studies is to serve the human to make them free from illness or prevention of the disease. For the medicine to serve its intended purpose they should be free from impurity, which might harm humans. Moreover, a large number of electroanalytical methods are available for quantification of pharmaceuticals. Electrochemical methods satisfy many of the requirements for such tasks for example selectivity, rapid response, high sensitivity, low cost, simplicity, and accuracy.
