How can commercially available Cu nanoparticles be incorporated with commercially available TIO2 nanoparticles?

Why does blocking with my immunogenic peptide cause nuclear fluorescence in ICC?

Hi all, I am validating a polyclonal antibody raised against human ANT4, through WB and ICC. In most of my controls, the antibody shows very little off-target binding, but when I pre-incubate the...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Does Napabucasin soluble in dichloromethane and in ethanol?

I need to prepare a solution of Napabucasin (inhibitor of cancer cell stemness) in dichloromethane. The drug is expensive, so maybe somebody already tried to do it. If it is soluble, what is the...

In order for copper atoms to penetrate the tittanium dioxide crystal lattice, you need to mix commercial nanoparticle powders and wait a very long time. Diffusion of atoms into solid bodies is very slow. It is possible to melt copper and then spray very fine nanoparticles onto the surface of titanium dioxide nanoparticles. Technologically, this process is very complex and you will not achieve uniform spraying.

Therefore, the answer to your question is unequivocal so it is impossible to obtain core/shell nanoparticles.

Dear colleague

May I suggest you to take contact with some french laboratories working on plasmonic signal of nanoparticules they synthetized. There is 2 teams in Lyon University: ENS (file attached) and Lumière Institute (https://ilm.univ-lyon1.fr/index.php?option=com_content&view=article&id=1043)

Good luck
