Designed and fabricated a custom 3-electrode system using AutoCAD, improving the detection sensitivity of albumin through EIS analysis

Conducted quantitative EIS analysis of albumin concentration using gold-deposited electrodes, validating the biosensor's performance 

Collaborated with Kyunghee University to measure and quantify albumin levels secreted by hepatocytes under normal and hypoxic conditions. 

Developed a urea biosensor by immobilizing enzymes on different membranes and optimizing sensitivity through membrane comparison.

Conducted measurements under flow conditions, utilizing surface modification techniques to enhance electrode performance.

Applied electrochemical analysis methods, including CV, EIS, and Amperometry, for biosensor characterization.

Utilized SEM, FTIR, and fluorescence microscopy for structural and chemical characterization of the modified electrodes.
