| titleOfInvention | METHOD FOR PRODUCING A MEMBRANE FOR AN ELECTROCHEMICAL OR OPTICAL SENSOR |
| abstract | A process comprises polymerising a mixt. of prepolymer and initiator, or solvent casting of preformed polymer soln. in a thin layer on a substrate; the novelty is that ionic sites are produced in the membrane by adding to the mixt. of starting materials a cpd. of formula R3X-Y (II); X is B, Al, N, P As or Sb; R is alkyl, aryl, haloalkyl, or haloaryl; Y is a gp. of formula -R2-CR1=CH2, -R3-OH, -R3-SH, -R3-NHR4, -R3-sugar, -R3-protein, -R3-NCO, -R3-NCS, -R5-Si(R6)n(R7)m, -R5-Si(R6)2-0-Si(R6)n(R7)m or -R6-Si(R6)2-NR8R9 (with R1 = H, alkyl, aryl, or Hal; R2 = -aryl-(CH2)p-, -aryl-(CH2)p-OCO-, -aryl-(CH2)p-O-CH2-, -(CH2)p-, -(CH2)p-OCO-, or -(CH2)p-O-CH2- (with p = 0 or above); R3, R5, R6 = alkyl, aryl or alkylaryl; R4 is H, alkyl or aryl; R7 = H, OH, O-alkyl, O-aryl, Hal, O-alkylaryl, NH2, NH-alkyl, NH-alkylaryl, N-dialkyl, N-diaryl, N(alkyl)(aryl), N(alkyl)(alkylaryl) N(aryl)(alkylaryl) or N-di(alkylaryl); R8 = -Si(R6)n(R7)m; R9 is H, R6 or R8; m is 1, 2 or 3; n is 3-m). Also claimed is a membrane (I) produced by the above process. (II) is Na-styryl-triphenyl-borate; the mixt. also contains an ionphore (III) so as to produce a membrane contg. both ionically charged gps. and specific ion-trapping gps. USE/ADVANTAGE - (I) are useful as membranes in ISFET based electrochcemical sensors; the process enables the introduction of covalently bonded ionic sites in (I); these sites determine the "permselectivity" of the membrane, i.e. its selectivity for cations or anions. The claims include an electrochemical sensor for measuring ionic concn. in a soln. contg. a sensor body with a membrane (I) thereon or therein, pref. an ISFET coated-wire electrode, commercial ion-sensitive electrode, sensor based on planar silicon technology or an optrode, with ratio (ionphore) (ionic sites) = 1-95(pref. 50) mol. |
