Preventing the spread of life-threatening gastrointestinal microbes on the surface of a continuously self-disinfecting block polymer
JOURNAL OF COLLOID AND INTERFACE SCIENCE, 652, 718–726.
author keywords: Anionic block polymer; Clostridioides difficile; Candida auris; Candida albicans; Antimicrobial; Self-disinfecting; Broad-spectrum; Infection prevention
TL;DR:
It is demonstrated that highly persistent, drug-resistant and transmissible healthcare pathogens such as Clostridioides difficile and Candida auris can be rapidly inactivated on the solid surface of a self-disinfecting anionic block polymer that inherently generates a water surface layer that is highly acidic (pH < 1) upon hydration.

Rapid and Repetitive Inactivation of SARS-CoV-2 and Human Coronavirus on Self-Disinfecting Anionic Polymers
ADVANCED SCIENCE, 8(11).
author keywords: antiviral materials; charged block polymers; microphase‐ ordered materials; polyanions; thermoplastic elastomers
MeSH headings : COVID-19 / prevention & control; COVID-19 / transmission; COVID-19 / virology; Disinfectants / therapeutic use; Humans; Pandemics; Polymers / chemistry; Polymers / therapeutic use; SARS-CoV-2 / drug effects; SARS-CoV-2 / pathogenicity
TL;DR:
It is demonstrated that an architecturally‐ and chemically‐diverse family of nanostructured anionic polymers yield a rapid and continuous disinfecting alternative to inactivate coronaviruses and prevent their transmission from contact with contaminated surfaces.

Toward Universal Photodynamic Coatings for Infection Control
FRONTIERS IN MEDICINE, 8.
author keywords: antimicrobial; Coronavirus; coatings; photodynamic inactivation; photosensitizer; polymer; singlet oxygen; Staphylococcus aureus
TL;DR:
The antimicrobial efficacy of a simple bicomponent spray coating composed of the commercially-available UV-photocrosslinkable polymer N-methyl-4(4'-formyl-styryl)pyridinium methosulfate acetal poly(vinyl alcohol) (SbQ-PVA) and one of three aPDI photosensitizers (PSs) is evaluated.

Photodynamic Coatings on Polymer Microfibers for Pathogen Inactivation: Effects of Application Method and Composition
ACS Applied Materials & Interfaces, 13(1), 155–163.
author keywords: hospital-acquired infections; photodynamic coatings; porphyrin photosensitizer; SARS-CoV-2 virus; polymer microfibers
MeSH headings : COVID-19 / prevention & control; COVID-19 / virology; Escherichia coli / drug effects; Escherichia coli / pathogenicity; Humans; Iatrogenic Disease / prevention & control; Light; Methicillin-Resistant Staphylococcus aureus / drug effects; Methicillin-Resistant Staphylococcus aureus / pathogenicity; Microfibrils / chemistry; Pandemics; Photosensitizing Agents / chemistry; Photosensitizing Agents / pharmacology; Polymers / chemistry; Polymers / pharmacology; Porphyrins / chemistry; Porphyrins / pharmacology; SARS-CoV-2 / drug effects; SARS-CoV-2 / pathogenicity; Singlet Oxygen
TL;DR:
These coated fibers can inactivate a human common cold coronavirus serving as a surrogate for the SARS-CoV-2 virus and are confirmed to be able to inactivate antibiotic-resistant bacteria.
