Summary

Traduction automatique

Her rapporterer vi protokollen for fabrikasjon av en Nafion-belagt, polyaniline-functionalized, electrochemically redusert Grafén og chemiresistive mikro pH sensor. Chemiresistor-basert, SSD mikro pH sensor kan oppdage pH endringer i sanntid under en Lactococcus lactis gjæringsprosess.
