最近在做RGO/AuNPs测试尿酸,在丝网印刷电极上进行电化学沉积,但是感觉没沉积上去,测试性能非常差,有时候低浓度电流比高浓度电流大,而又的时候高浓度电流比低浓度的电流大,很惆怅,想请问下大神们,有人做过?救救孩子吧,多多给建议,谢谢!!!
the solution containing 0.1 wt% HAuCl4 and 0.8 mg mL−1 GO was prepared.To modify the working electrode of uric acid sensor, the solution containing 0.1 wt% HAuCl4 and 0.8 mg mL−1 GO was prepared.(这是参考文献中配方)
电沉积采用CV,参数:-1.8-0V,扫速:50mv/s,一共5圈
