研究目的
Developing a cheap, rapid, stable, reliable and accurate glucose sensing system for diagnosis of diabetes.
研究成果
The flexible Cu NPs-LIG sensor exhibits excellent sensitivity, rapid response, low detection limit, and good selectivity for glucose detection, making it a promising candidate for wearable and implantable glucose monitoring devices.
研究不足
The study does not extensively explore the long-term stability under varying environmental conditions or the sensor's performance in complex biological matrices beyond serum samples.
1：Experimental Design and Method Selection:
The study employs a substrate-assisted electroless deposition (SAED) technique to anchor Cu nanoparticles on laser-induced graphene (LIG) for glucose sensing.
2：Sample Selection and Data Sources:
Commercial PI film (KAPTON) is used as the substrate for LIG fabrication.
3：List of Experimental Equipment and Materials:
Includes a portable laser scribing system, SEM, TEM, XRD, Raman spectrometer, XPS, and electrochemical analyzer.
4：Experimental Procedures and Operational Workflow:
Involves laser scribing PI films to form LIG, SAED process to deposit Cu NPs, and electrochemical measurements for glucose detection.
5：Data Analysis Methods:
Cyclic voltammetry and amperometric experiments are used to analyze the sensor's performance.
