Competing interests
: The Authors declare no other financial and non-financial competing interests except the following: 1. Published patent PCT/SG2024/050366 titled Main Chain Cationic Oligo(Imidazolium) Forms N-Heterocyclic Carbene For Effective Bacterial Killing In Complex Environment is associated with this work. The applicants are NTU and Imperial College Innovations Limited, and the inventors include M.B.C., K.P., A. Gründling, C.H.K., M.R.L., Z.Y.K., G.W., and M.B.T. The patent covers the novel compound composition (1-13): their syntheses, characterizations (including NHC formation of 1-2 and 5), in vitro studies, and mastitis studies, but not the mice data and not some of the NHC-assisted model translocation data. 2. Unpublished patent (Singapore provisional patent application number 10202500296 V) titled OIM1-6-1X is associated with this work. The applicant is NTU and the inventors include M.B.C., M.R.L., Z.W., C.T., Q.H.N.V., G.W., S.H.T., and C.H.K. The patent covers the novel compound composition (12): their syntheses, and in vitro MIC and toxicity characterizations. 3. Published patent PCT/SG2023/050007 titled Polyimidazolium-based Cationic Antimicrobial Polymers for Novel Mastitis Prophylactic Solutions is relevant to this manuscript. The applicants are MIT and NTU, and the inventors include M.B.C., P.H.T., Z.K., and Ferguson, Michelle, and Elizabeth. The patent covers mastitis studies.
