Hello Savy Panamkuttiyiel Minal,

The raised topic is interesting. In order to have better visibility, it is necessary to apply a coating with metal nano particles. Most often, the metal coating is made of gold due to its good conductivity and does not react with the biomaterials. Problem remains the size of particles that can change surface roughness because they are not the same size. may even block some openings. That's why the share of metal particles could be best. for analysis. This joints in special conditions with pre-fitted vacuum installations.

Wishing for success in scientific work.

Dear Sir,

I have coated the fabric with metal nanoparticles. For their characterization with SEM-EDX, Do i have to further coat them with gold sputter coating? Or it will be sufficiently visible due to metal nanoparticles coating, which i need to characterize. This is my main question. Although I can find out its answer once I go to the facility but since the facility is out of City I needed to confirm it before booking a slot.

Thanks

Regards

Every metal coating will do the job to investigate the object. However, due to the different conductivity of metals (metallic coatings), the conductivity changes and the image is visible in the dark (dark). Therefore, current must be lifted and this may damage the subject.

I haven't done it yet but I think the most suitable thing is to first perform the edx analysis and then follow the standard process to gold coat the fabric for the SEM imaging...
