Bioelectrocatalytic platforms based on chemically modified nanodiamonds by diazonium salt chemistry

Detonation nanodiamonds immobilized onto screen-printed gold electrodes have been modified with a phenothiazine (Azure A) by electrografting of the corresponding in situ generated diazonium salt in acidic medium in the presence of nitrite. The resulting disposable electrochemical platform has been…

Bifunctional Tm3+,Yb3+:GdVO4@SiO2 Core-Shell Nanoparticles in HeLa Cells: Upconversion Luminescence Nanothermometry in the First Biological Window and Biolabelling in the Visible

The bifunctional possibilities of Tm,Yb:GdVO4@SiO2 core-shell nanoparticles for temperature sensing by using the near-infrared (NIR)-excited upconversion emissions in the first biological window, and biolabeling through the visible emissions they generate, were investigated. (244 characters)

Benefits of Silica Core–Shell Structures on the Temperature Sensing Properties of Er,Yb:GdVO4 Up-Conversion Nanoparticles

We studied the temperature-dependent luminescence of GdVO4 nanoparticles co-doped with Er3+ (1 mol %) and Yb3+ (20 mol %) and determined their thermal sensing properties through the fluorescence intensity ratio (FIR) technique. We also analyzed how a silica coating, in…

Bactericides Based on Copper Nanoparticles Restrain Growth of Important Plant Pathogens

Copper nanoparticles (CuNPs) can offer an alternative to conventional copper bactericides and possibly slow down the development of bacterial resistance. This will consequently lower the accumulation rate of copper to soil and water and lower the environmental and health burden…

Asymmetrical flow field flow fractionation methods to characterize submicron particles: application to carbon-based aggregates and nanoplastics

In the last 10 years, asymmetrical flow field flow fractionation (AF4) has been one of the most promising approaches to characterize colloidal particles. Nevertheless, despite its potentialities, it is still considered a complex technique to set up, and the theory…
