Magneto-plasmonic nanoparticles were fabricated using a 1064 nm picosecond-pulsed laser for ablation of Fe/Au and Fe/Au/Fe composite thin films in acetone. Nanoparticles were characterized by electron microscopy, ultraviolet-visible (UV-VIS) absorption, and Raman spectroscopy. Hybrid nanoparticles were arranged on an aluminum substrate by a magneti...
Conference Paper
Surface-enhanced Raman spectroscopy (SERS) is a highly specific method to investigate and characterize biological molecules such as nucleic acids, proteins, lipids. This method can be combined with electrochemistry and performed in situ, thus bringing information about bonding, intra and extra-molecular interactions, and interaction with component...

In this research, we have demonstrated that 2D Ti3C2Xn-based MXene (MXene) films are suitable for the design of surface-enhanced Raman spectroscopy (SERS)-based sensors. The enhanced SERS signal was observed for a salicylic acid molecule on Ti3C2Tx-based MXene film. Confirmation of the adsorption of the salicylic acid molecule and the formation of...
Conference Paper
The goal of this study is development of ultra-sensitive and reproducible SERS platform based on novel magnetoplasmonic nanoparticles produced by laser ablation. The magnetic part of hybrid nanoparticles ensures manipulation of the nanoparticles by magnetic field by arranging them at biological surfaces in a special geometry resulting in high and r...

... The changes in the strengths of the a and b peaks indirectly proved the etching of Al layers and the decrease in terminal functional groups (-F and -OH). Meanwhile, the peak intensity, at approximately 153 cm −1 , belonged to Ti 3 C 2 T x MXene oxidation and the formation of the TiO 2 [15]. The two broad peaks at 1350 and 1580 cm −1 were assigned to the D and G bands of graphitic carbon, respectively. ...
