WebWhat are ionophores? Ionophores are lipid-soluble molecules, usually synthesized by microorganisms to transport ions through a lipid bilayer of cell membrane. Ion Transport Ionophores function as ion carriers. Ion carriers can transfer ions from a hydrophilic medium, such as water, into a hydrophobic medium, i.e a biological membrane, where … Web15 mrt. 2024 · For ion sensing, polymeric nanosensors commonly use an ionophore-based detection mechanism. This consists of an ion-binding molecule (“ionophore”) for analyte recognition coupled to a pH-responsive fluorescent molecule for signal transduction through maintaining a charge-balance in the organic phase.
