ABSTRACT: Clinical steel work surfaces lack inherent antimicrobial properties and present low friction coefficients, creating traction deficiencies and sanitary vulnerabilities. This review synthesises recent advancements in multifunctional organic coatings engineered to replace pristine metallic substrates. We evaluate the chemical integration of quaternary ammonium compounds (QACs), metal-oxide resins, and structural MXene nanosheets within polymer matrices. Furthermore, we analyse how micro-textured topographies balance anti-biofluid accumulation with tactile mechanical traction. Finally, we outline structural strategies to optimize long-term mechanical, chemical, and thermal coating resilience.
