Fragmentation of colloidal silver nanoparticles employing ultrafast laser pulses (fs-colloid)

   

Project no.: 09.3.3-LMT-K-712-15-0083

Project description:

Nowadays, nanomaterials and nanoproducts have become an indispensable part of our daily lives. Metal nanoparticles possessing surface plasmon resonance property are expected to be used in photothermal therapy for the treatment of oncological diseases, single cell imaging, etc. As the electrical, optical, and mechanical properties of nanometric particles are extremely sensitive to linear dimensions, the scientific community is intensively searching for synthesis methods that would ensure the monodispersity of nanoparticles that would be suitable also for industrial production. Colloidal nanoparticles are usually formed by chemical synthesis, but the disadvantage of synthesis is that the particles are not always uniformly sized. One way to control the size distribution of nanoparticles is by laser fragmentation in a liquid using ultra-short pulses. During the practice, chemical synthesis of silver nanoparticles will be performed and the particle size distribution will be modified by ultrashort (fs-duration) laser pulses.

Project funding:

Project is funded by EU Structural Funds according to the 2014–2020 Operational Programme for the European Union Funds’ Investments priority “Development of scientific competence of researchers, other researchers, students through practical scientific activities” under Measure No. 09.3.3-LMT-K-712.


Project results:

During the internship the student will improve her scientific qualification by mastering the methodology of chemical synthesis of silver nanoparticles, getting acquainted with the ultrashort pulse laser effect mechanisms for modification of particle size distribution. After accomplishing experimental research student will determine optimal parameters for modification of colloidal solution using ultrashort pulse exposure.
