Summary: This study examined two types of carbon-based nanoparticles (CNPs) with gadolinium (Gd) impurities (Gd-CNPs), synthesized through microwave synthesis (MWS) and hydrothermal synthesis (HTS), for their potential applications as photoluminescent (PL) labels and contrast agents in magnetic resonance imaging (MRI). The synthesized Gd-CNPs were characterized using various techniques and their specific features and functional properties were revealed. The results showed that the MWS samples had higher absorption and stronger PL in the visible and near-infrared (NIR) spectral regions, and lower longitudinal and transverse relaxivities compared to the HTS samples, indicating their suitability for bimodal bioimaging applications.

Summary: Ultrapure composite nanostructures combining semiconductor and metallic elements, synthesized by ultrafast laser processing, are important for applications in high chemical purity fields. Although these nanocrystals have shown prospects in plasmonic biosensing, the structure and control of their properties remain challenging due to the lack of research in this area. In this study, silicon-gold nanoparticles were synthesized using various approaches and their plasmonic and paramagnetic properties were observed. The impact of laser ablation time on the nanoparticles' stability and concentration, as well as their optical properties and electrical conductivity, were studied. These results contribute to a better understanding and control of the laser-assisted synthesis of semiconductor-metallic nanocomposites for future applications.

Summary: Temperature dependent X-ray photoemission spectroscopy (XPS) was used to study the spin-crossover (SCO) transition in the nanocrystals of 3D Hoffman-like {Fe(pz)[Pt(CN)(4)]}. The temperature-dependent variations in the Fe 2p core-level spectrum provide clear evidence of the spin-state transition in this SCO complex. The lack of discernible temperature-driven shifts in the binding energies of the N 1s core-level components may be due to the immunity of its HS electronic configuration to thermal fluctuations. The high-spin fraction versus temperature plot extracted from XPS measurements indicates that the surface of the nanocrystals of {Fe(pz)[Pt(CN)(4)]} is in the high-spin state at room temperature, making it promising for room-temperature spintronics and quantum information science applications.

Summary: The production of non-toxic and homogeneous colloidal solutions of nanoparticles (NPs) is crucial for biomedical applications. Pulsed laser ablation in liquids (PLAL) is a powerful and efficient method for generating chemically pure silicon nanoparticles. However, controlling the final characteristics of the particles and achieving a narrow size distribution in the colloidal solutions is challenging. Fragmentation of NPs obtained through laser irradiation can be utilized, but the resulting NP characteristics depend on laser irradiation parameters and material properties. Therefore, understanding the mechanism of NP fragmentation is important for generating colloidal solutions with desired properties.
