Abstract

Nanoporous carbon materials are highly important materials for a wide array of applications. Here we show that nanoporous carbon can act as highly active materials for electrochemical sensing. We observed that nanoporous carbon material exhibits a faster heterogeneous electron transfer than graphite and pure carbon nanotubes. Nanoporous carbon exhibits a superior electrochemical performance for sensing of important biomarkers such as dopamine, ascorbic acid, uric acid, NADH, DNA bases, and forensic-related compounds such as nitroaromatic explosives. Nanoporezní materiály na bázi uhlíku nacházejí využití v mnoha oblastech. V tomto článku ukážeme jejich vý hody pro použití v oblasti electrochemického stanovení látek. Heterogenní přenos elektronu mezi nanoporézním uhlíkem a solutem je velmi rychlý . Použití tohoto typu uhlíku je velmi vý hodné pro stanovení dopaminu, vitamínu C, kyseliny močové, NADH, DNA bází a nitroaromatický ch látek. A great sense of achievement! The performance of nanoporous carbon as an electrode material was investigated and compared with that of bare glassy carbon, graphite microparticles, and carbon nanotubes. Nanoporous carbon was found to exhibit the highest heterogeneous electron transfer (HET) rate among these materials, thus sensing analytes such as NADH, DNA bases, and 2,4,6-trinitrotoluene (TNT) with an improved electrochemical response.
