copper(1) iodide or cuprous iodide
On our recent FB live, I spoke a bit about Copper Iodine and how to make it. https://www.facebook.com/1033169015/videos/3163078403989499/

COPPER(I) IODIDE
Synonym: cuprous iodide
“Uses
The iodide salt is used as a source of dietary iodine in table salt and animal feed; in cloud seeding; as a coating in cathode ray tubes; as a temperature indicator; and as a catalyst in organic reactions.Copper(I) iodide is found in nature as mineral marshite.”

Efficacy of copper and silver ions with iodine in the inactivation of Pseudomonas cepacia
https://pubmed.ncbi.nlm.nih.gov/1371772/
“These results, along with published data, suggest that the combination of these metals with halogenation may have applications in the disinfection of both recreational and potable water.”
Investigation of the antiviral properties of copper iodide nanoparticles against feline calicivirus
https://pubmed.ncbi.nlm.nih.gov/22227118/
“This study demonstrated the antiviral properties of copper iodide (CuI) nanoparticles against the non-enveloped virus feline calicivirus (FCV) as a surrogate for human norovirus.”
Novel antiviral characteristics of nanosized copper(I) iodide particles showing inactivation activity against 2009 pandemic H1N1 influenza virus (2012)
https://pubmed.ncbi.nlm.nih.gov/22156433/
“We confirmed that CuI particles showed antiviral activity…”
“Taken together, these findings indicate that CuI particles exert antiviral activity by generating hydroxyl radicals. Thus, CuI may be a useful material for protecting against viral attacks and may be suitable for applications such as filters, face masks, protective clothing, and kitchen cloths.”
A novel study of antibacterial activity of copper iodide nanoparticle mediated by DNA and membrane damage
https://pubmed.ncbi.nlm.nih.gov/22521682/
“In this article potential activity of nanoparticles (NPs) of copper iodide (CuI) as an antibacterial agent has been presented.”
“These NPs are able to kill both gram positive and gram negative bacteria.”
Assessing the Antimicrobial Properties of Copper-Iodide Doped Adhesives in an In vitro Caries Model: A Pilot Study
https://pubmed.ncbi.nlm.nih.gov/35846577/
“CuI adhesives with 5 mg/ml or higher have the potential to limit tooth demineralization…”
https://pubmed.ncbi.nlm.nih.gov/35864980/ (2021)
“Anti-bacterial studies showed copper iodide particles to be a potent antimicrobial agent.”

“In the laboratory however, copper(I) iodide is prepared by simply mixing an aqueous solution of potassium iodide and a soluble copper(II) salt such copper sulfate.[11]
Cu2+ + 2I− → CuI + 0.5 I2″
…
“Copper(I) iodide reacts with mercury vapors to form copper tetraiodomercurate:
4 CuI + Hg → Cu2HgI4 + 2 Cu
This reaction can be used for the detection of mercury since the white (CuI) to brown (Cu2HgI4) color change is dramatic.”
CuI is used as a source of dietary iodine in table salt and animal feed.[19]
