研究目的
Investigating the use of laser-induced graphene (LIG) stamp for high-performance electrochemical sensing applications, specifically for hydrogen peroxide detection.
研究成果
The developed LIG stamp method successfully improved the electrical and electrochemical properties of the electrode, showing high sensitivity and a wide linear range for hydrogen peroxide detection. Future work aims to achieve more uniform distribution of LIG particles on the electrode.
研究不足
The LIG porous particles were not uniformly distributed on the Au electrode, leading to background current during amperometric measurement. Detection limit could be improved with more uniform distribution.
1：Experimental Design and Method Selection:
The study involved the fabrication of a LIG stamp to transfer LIG onto an Au substrate, followed by electrodeposition of Pt nanoparticles (PtNPs) for biosensor applications.
2：Sample Selection and Data Sources:
Kapton polyimide was used as a precursor for LIG, and water-soluble tape was used for transferring LIG onto Au substrates.
3：List of Experimental Equipment and Materials:
CO2 IR laser inducing machine, XPS, Raman spectroscopy, and electrochemical workstation were used.
4：Experimental Procedures and Operational Workflow:
The process included laser scanning on PI film, transferring LIG onto Au electrode using water-soluble tape, and electrodepositing PtNPs.
5：Data Analysis Methods:
Cyclic voltammetry and amperometric measurements were used for electrochemical characterization.
