Combinatorial Synthesis of Next Generation Water‐Soluble Quaternized N‐Halamine Oligomers with Long‐Lasting Antiviral Properties (Adv. Funct. Mater. 28/2026)

Long-Lasting Dual-Functional Antiviral Oligomers In their Research Article (10.1002/adfm.202506704), Shady Farah and co-authors successfully develop a library of dual-functional antiviral oligomers incorporating N-halamine and quaternary ammonium functionalities for long-lasting antiviral activity. The leading materials exhibit rapid and durable antiviral activity against SARS-CoV-2 variants and influenza H1N1, with 4 to 5 log reduction in viral copies at 5 mg mL−1 concentration, surpassing household bleach, while remaining non-toxic to human cells.
