Electrochemiska sensorer för marina miljöer förlorar snabbt sitt signal när marina mikroorganismer täcker upp dem — ett problem som begränsar långtidsövervakning av jonkoncentrationer. Forskare vid Qingdao University of Science and Technology har utvecklat en självreparerande sensor för kaliumjoner som motverkar denna biofouling genom ett peptidhydrogelskikt baserat på Fmoc-FF-dipeptider. Sensorn uppnår en signaldrift på endast 0,2 mV per timme under 24 timmar — betydligt bättre än konventionella elektroder. Arbetet genomfördes i samarbete med KTH och spanska universitet. Fyndet är relevant för alla som värderar marina sensor-IoT-system eller övervakar vattenkvalitet i kustnära områden. Självreparerande material minskar behovet av ofta utbytade sensorelement, vilket sänker driftskostnader och möjliggör äkta långtidsövervakning. För leverantörer av miljösensorik öppnas nya marknader inom akvakultur och kustövervakning.
