The determination is accomplished by amperometry using tetramethylbenzidine and h2o2 as the substrates . two different graphite pastes were compared using either sol - gel or solid paraffin as binders . the sol - gel biocomposite showed a better response characteristics and higher reproducibility 我們比較了用溶膠-凝膠和固體石蠟為基質(zhì)的免疫電極的不同特性,其中溶膠-凝膠免疫電極表現(xiàn)出更好的響應(yīng)特性和更高的重現(xiàn)性,能檢測(cè)到的nd
