    Abstract: Some variations provide a sensing system configured to measure the concentration of an antimicrobial agent in a polymer, comprising: a polymer containing (i) a discrete solid structural phase comprising a solid structural polymer and (ii) a continuous transport phase comprising a solid transport polymer and capable of containing the antimicrobial agent; and an antimicrobial-agent sensor that chemically senses the antimicrobial agent. The antimicrobial-agent sensor is disposed on a surface of, and in mass transport with, the polymer. The antimicrobial-agent sensor contains a responsive material disposed on or within a carrier material. The responsive material is chemically reactive with the antimicrobial agent and exhibits an observable and quantifiable property change upon chemically reacting with the antimicrobial agent. The observable and quantifiable property change may involve chromaticity, optical transparency, ionic conductivity, or electronic conductivity, for example. Some variations provide methods of making and/or using the sensing system.

    Abstract: The present invention provides: a surface treatment liquid which is capable of performing good hydrophilization or hydrophobization of the surface of an object to be treated even if the surface treatment liquid does not contain a coating film-forming resin; and a surface treatment method which uses this surface treatment liquid, A surface treatment liquid, comprising a resin (A) and a solvent (C), and wherein a resin having a functional group I that is a nitrogen-containing heterocyclic group and a functional group II that is a functional group other than the functional group I and having one or more groups selected from among hydrophilic groups and hydrophobic groups, and comprising a constituent unit (a1) having the functional group I, and one or more constituent units selected from the group consisting of a constituent unit (a2) having a cationic group in a side chain, and a constituent unit (a3) having an anionic group in a side chain, is used as the resin (A).
