11. Summary of the new findings of the thesis

- Successfully fabricate Ag and Au nanostructures in ethanol, water and PVP by using Laser technology to effectively study MEF and SERS effects.

- Surveyed and clarified some properties of the Fluorescence Enhancement effect in some material such as RhB, ZnO and ZnS:Mn using Au, Ag metal nanostructures synthesized by Pulsed Laser Ablation method in water, ethanol and PVP.

- Successfully fabricated SERS substrates using Au, Ag nanostructures on laser ablated Cu plates with high SERS enhancement factors (EF > 10⁶) and high repeatability.

- Successfully fabricated SERS substrates using Au, Ag nanostructures on laser ablated Si plates with high SERS enhancement factors (EF > 10⁷) and high repeatability.

- Developed a procedure to determine tetracycline antibiotic residues up to 0.1 ppm in shrimp using AgNPs/aSi sensor made by Pulsed Laser Ablation method and a portable spectrometer. This new result has never been previously published on any study which determines Tetracycline in shrimp using the SERS method.

12. Practical applicability, if any:

- The system configuration and procedures to synthesis metal nanoparticles using Laser technology can generate optimal metal nanoparticles for MEF and SERS effects.

- The SERS substrates created by laser technology are applicable for detecting antibiotic residues and food protection chemicals in food safety and hygiene economies.

13. Further research directions, if any

- Continue to study and optimize the fabrication process of metal nanostructures by PLA method for SERS and MEF applications, develop SERS sensors with high EF and repeatability, in which Au-Ag bimetallic nanostructures can be used due to their variable plasmon absorption wavelengths.

- Continue to study the application of SERS and MEF spectroscopy methods on other material such as antibiotics, plant protection substances in food, etc., orienting their application in food safety and hygiene.
