Research concerning biofilm control is critical due to the pervasive and resilient nature of biofilms, which pose significant challenges across industrial, environmental, healthcare sectors. Traditional antimicrobial treatments are often ineffective against these robust structures. Here, we explore properties ionic liquids (ILs) their efficacy in disruption. By examining structural variations ILs, highlight key role hydrophobicity, noting that longer alkyl side chains IL cations enhance disruption bacterial death. However, upon reaching a certain optimal chain length─usually C12 C14─the activity ILs starts decrease. Furthermore, symmetry size anions significantly impact elimination. This Perspective addresses gap research, revealing structure–activity relationships providing foundation for designing more effective biofilm-disrupting agents.

Abstract Surface treatment of textiles causes a significant amount environmental pollution and endowing traditional fabrics with multiple functions through facile methods remains challenging. Here simple strategy is proposed involving the copolymerization methacrylic acid (MA) functionalized cotton fabric (CF) vinyl‐functionalized ionic liquid (IL). The resulting CF‐PIL (where P refers to poly) shows high bacteriostatic reduction rates (BR > 99%), excellent flame retardancy (LOI = 28.1%), together sensitivity quick responsiveness. exhibits unparalleled reliability even after 50 washing cycles. CF‐PIL‐based also captures signals from mechanical stimuli, humidity, temperature. This allows material act as sensor for physiological signal monitoring (breathing, body temperature, external stimulation), high‐temperature. Through design circuit, assembled high‐temperature fire alarm system, which can provide early warning temperatures when near or in contact flames within few seconds. While many applications may be envisaged, particular relevance are intelligent firefighting suits smart architectural textiles.

Understanding the interactions between ionic liquids (ILs) and biomembranes is pivotal for uncovering origins of IL-induced biological activities their potential applications in pharmaceuticals. In this study, we investigate influence imidazolium-based ILs on viscoelasticity, dynamics, phase behavior two model membrane systems: (i) lipid monolayers (ii) unilamellar vesicles, both composed dipalmitoylphosphatidylcholine (DPPC). Two different with varying alkyl chain lengths, namely, 1-decyl-3-methylimidazolium bromide (DMIM[Br]) 1-hexyl-3-methylimidazolium (HMIM[Br]) are used to role lengths. Our findings demonstrate that induce significant disorder membranes by altering area per molecule, thereby modulating viscoelastic properties. a longer show stronger membranes, causing more pronounced disorder. Fourier transform infrared spectroscopy indicates IL incorporation shifts membrane's main transition lower temperatures introduces gauche defects, signifying increased structural This effect amplified chains higher concentrations. Quasielastic neutron scattering studies highlight markedly enhance lateral diffusion lipids within leaflet, extent enhancement determined physical state, concentration, length. The most acceleration occurs ordered concentrations longer-chain IL. Molecular dynamics simulations corroborate these experimental findings, showing extensively disrupt organization, introduce increase lipid, consequently diffusion. fluidity permeability provides mechanistic basis observed toxicity associated ILs. These results offer critical insights into molecular-level advancing our understanding toxicological pharmaceutical implications.

Ionic liquids (ILs) have promising applications in pharmaceuticals and green chemistry, but their use is limited by toxicity concerns, mainly due to interactions with cell membranes. This study examines the effects of imidazolium-based ILs on microscopic structure phase behavior a model membrane composed zwitterionic dipalmitoylphosphatidylcholine (DPPC) lipids. Small-angle neutron scattering dynamic light reveal that shorter-chain IL, 1-hexyl-3-methylimidazolium bromide (HMIM[Br]), induces aggregation DPPC unilamellar vesicles. In contrast, this absent longer alkyl chain 1-decyl-3-methylimidazolium (DMIM[Br]). Instead, DMIM[Br] incorporation leads formation distinct IL-poor IL-rich nanodomains within membrane, as evidenced X-ray reflectivity, differential scanning calorimetry, molecular dynamics simulations. The less evident nanodomain HMIM[Br] underscores role hydrophobic between lipid tails ILs. Our findings demonstrate chains significantly enhance propensity form nanodomains, which closely linked enhanced permeability, shown dye leakage measurements. heightened permeability likely underlies greater cytotoxicity longer-chain crucial link provides valuable insights for designing safer, more environmentally friendly ILs, promoting biomedical sustainable industrial processes.
