Porous carbon supported nanoceria derived from one step in situ pyrolysis of Jerusalem artichoke stalk for functionalization of solution-gated graphene transistors for real-time detection of lactic acid from cancer cell metabolism.

肿瘤细胞生物标志物的有效检测备受关注。本文成功制备了一种基于溶液门控石墨烯晶体管（SGGT）的高灵敏生物传感器，用于检测肿瘤细胞糖酵解代谢在细胞周围积累的乳酸含量。该乳酸传感器的传感机制归因于乳酸氧化酶（LOD）氧化乳酸产生的过氧化氢（H2O2）在门电极附近发生电化学催化。传感器的关键组分是由菊芋秸秆经一步原位热解制备的负载氧化铈纳...
