Disclosed are a pharmaceutical use of a gold cluster for the treatment of multiple sclerosis in a subject. The gold cluster comprises a gold core and a ligand bonded to the gold core.

Antimicrobial compositions for killing or deactivating microbes, such as viruses, bacteria, or fungi, include metal nanoparticles, a carrier, and a plurality of metal nanoparticles. The nanoparticles can be selected to have a particle size and particle size distribution to selectively and preferentially kill one of a virus, a bacterium, or a fungus. Antiviral compositions can include nanoparticles having a particle size of 8 nm or less, 1-7 nm, 2-6.5 nm, or 3-6 nm. Antibacterial compositions can include nanoparticles having a particle size of 3-14 nm, 5-13 nm, 7-12 nm, or 8-10 nm. Antifungal compositions can include nanoparticles having a particle size of 9-20 nm, 10-18 nm, 11-16 nm, or 12-15 nm.

An embodiment provides a method for treatment of a viral antigen for the COVID-19 virus, including: obtaining a body fluid from a patient; introducing the body fluid to at least one binding antibody, wherein the at least one binding antibody binds to an antigen of the SARS-CoV-2 spike (S) protein and comprises a conjugated metal; forming a viral antigen-antibody complex; and removing the viral antigen-antibody complex from the body fluid using a radiofrequency method; and returning the body fluid to the patient. Other aspects are described and claimed.

A method of preparing biocompatible and stable gold nanoparticles comprises preparing at least one flavonoid-rich plant extract, and mixing at least one of the plant extracts with an aqueous solution of at least one gold salt. The flavonoid-rich plant extract is an extract of Hubertia ambavilla or Hypericum lanceolatum. The gold nanoparticles may be used for medical and/or cosmetic purposes.
