11. Summary of the new findings of the thesis

- Successfully fabricated a glucose oxidase (GOx)-based enzymatic glucose sensor using PbS nanoparticles synthesized via laser annealing-modified sonochemical method. Maximum sensitivity of the sensor was 546,2 µAcm-2mM-1.

- The direct interaction between the PbS nanoparticles and SH-containing organic materials was estimated by ab initio calculation, which consequently lead to the charge-transfer between the nanoparticles and organic molecules and gave explanation to the sensitivity enhancement of the PbS-based enzymatic glucose sensor.

- Successfully fabricated a stem-cell counting system, in which the blood stem cells concentration from bone-marrow was determined by total impedance method after being collected by Fe3O4-Ag – activated magnetic separation.

- The conjugation efficiency between the Fe3O4-Ag nanoparticles and the anti-CD34 antibody was firstly estimated by using the magnetic property of the particles and fluorescence of the ECD dye that linked with the antibody.
