In this study,a novel nonenzymatic electrochemiluminescence (ECL) glucose biosensor based on LaTiO3-Ag0.1(LTA) modified electrode was developed.The morphology,composition and electrochemical behaviors of the perovskite LaTiO3-Ag0.1 nanomaterials were characterized and investigated respectivly.Based on ECL experimental results,the perovskite LaTiO3-Ag0.1 nanomaterials modified electrode displayed high electrocatalytic activity towards the oxidation of glucose.Under optimal conditions,compared with previous reports on similar nonenzymatic ECL glucose sensors,this sensor showed lower detection limit,higher sensitivity,and much wider linear range.A simple and promising nonenzymatic electrochemiluminescence glucose biosensor based on LTA modified at the surface of the GCE was demonstrated.

锂离子电池的能量密度只是汽油的百分之几,但锂离子电池的能量储存部分与能量转化部分存在于同一空间之内.如果由于制作不良、误操作或局部热点引起内部或外部短路,所存能量将在局部集中释放,引起局部过热,进而引起连锁放热反应,最后引起电解液本身的分解、燃烧反应(其发热量远远大于电池所存储的电能),造成冒烟、失火甚至爆炸等热失控事件.

亚硝酸盐是作为一种允许使用的食品添加剂,在控制的安全范围内使用不会对人体造成危害.但摄入过量的亚硝酸盐,血红蛋白的亚铁将氧化为高铁状态,从而形成不能送氧的高铁血红蛋白;高铁血红蛋白达到30％～50％时,可导致贫血性缺血,造成全身各组织特别是脑组织的急性损害,出现呼吸困难,神经机能紊乱,甚至死亡[1].
众所周知,经常与空气中的颗粒物质接触能够引发一系列的疾病,包括心血管疾病,呼吸道疾病以及肺癌[1].颗粒物质能够导致这些疾病产生的主要原因在于它们的颗粒直径都小于等于10微米,能够通过喉咙、鼻子直接进入肺部扰乱机体的正常生理功能.一些文献已经报道了许多颗粒物质具有基因毒性,能够氧化损伤DNA、导致染色体突变等[2].
