研究目的
Investigating the synthesis of Carbon Nanoparticles (CNPs) by laser ablation of coconut shell charcoal in liquids and their application in glucose sensing.
研究成果
CNPs synthesized from coconut shell charcoal by laser ablation in ethanol and water showed potential for glucose sensing applications, with good sensitivity and selectivity. The sensor exhibited a wide linear range of detection and was fabricated without the use of any binder or enzymes.
研究不足
The study focuses on the synthesis and application of CNPs for glucose sensing but does not explore the potential toxicity or long-term stability of the CNPs in biological systems.
1：Experimental Design and Method Selection:
Laser ablation in liquid method was used for synthesizing CNPs from coconut shell charcoal in ethanol and water media.
2：Sample Selection and Data Sources:
Commercially available coconut shell charcoal was powdered and used as the source material.
3：List of Experimental Equipment and Materials:
Pulsed Nd:YAG Laser (1064 nm), double beam spectrometer (JASCO V-670), spectrophotometer (JASCO FP 8500), high resolution transmission electron microscope (HRTEM) (JOEL 2010, 200 kV).
4：Experimental Procedures and Operational Workflow:
The powdered coconut shell charcoal was irradiated with laser in ethanol and water, followed by centrifugation and characterization.
5：Data Analysis Methods:
Optical absorption spectra, photoluminescence study, and HRTEM analysis were conducted to characterize the CNPs.
