A micro ammoniasensor, consisting of an ISFET covered with a dry membrane which is made from nonactin and substituted poly-..gamma..-methyl-L-glutamate (PMG) is described. The gate output voltage of the micro ammonia sensor increased with NH/sub 4/OH addition. The response time of the sensor was 2 min at 30/sup 0/C, and the sensor exhibited superior selectivity for NH/sub 4//sup +/ compared to a pH sensitive ISFET.
