柔性石墨片(FGS)具備優(yōu)良的導(dǎo)電性與柔韌性,可作為葡萄糖傳感器的自支撐載體,解決由于使用黏結(jié)劑降低傳感器性能的問題。本文采用水熱法,使用抗壞血酸還原硫酸銅,在FGS上復(fù)合銅納米顆粒構(gòu)建Cu/FGS自支撐無酶葡萄糖傳感器,在線性范圍0.1～3.4 mmol/L內(nèi)具有較高的靈敏度7 254.1μA·mM^-1·cm^-2(R²=0.996 1),較低的檢測限1.05μmol/L;在線性范圍3.4～5.6 mmol/L靈敏度為3 804.5μA·mM^-1·cm^-2(R²=0.9995)。此外,該電極還有較好的抗干擾性、重復(fù)性及穩(wěn)定性。
