This localized enhancement led to the initial interest in the use of Raman spectroscopy to probe the specific environment of the nanoparticle. The authors have no relevant affiliations or ...

2013;8(8):1335-1351. Spontaneous Raman spectroscopy has, therefore, already been demonstrated to be a chemically specific method for investigating nanoparticle interactions and to probe the ...

While gold, silver and palladium are subject to their own forms of volatility, many believe them to be superior long-term investment choices for retaining and growing value. You can’t hold ...

The French biotech company Nanobiotix announced today that it has dosed the first patient in the CONVERGE study, a Phase 2 randomized controlled clinical trial evaluating its potentially ...

Where does the world get its silver? In 2023, silver mines produced 830.5 million ounces of silver. That total is projected to decline by about 1 percent to 823.5 million ounces in 2024.

Techniques such as modifying metal nanoparticles with metal–organic frameworks (MOFs), applying ... Among noble metals, silver is particularly valued for its ability to generate strong LSPR, which ...

Cytotoxicity and phytotoxicity are also associated with silver nanoparticles (AgNPs). For instance, biogenic AgNPs synthesized using Aloe vera extract caused significant injury to Brassica seedlings ...
