Through the study of mineragraphy and electron probe microanalysis, we found the existential status of silver having two types-visible and invisible, with mainly visible silver.

The probes are increasingly being used in countries that were until recently only using microscopy to diagnose tuberculosis.

However, instead of heating the entire sample, the researchers used a hot atomic force microscope (AFM) tip to convert very narrow ribbons, measuring just 12 nm across, into reduced graphene.
