Sensitive photoelectrochemical(PEC) bioanalysis usually relies on enzyme-assisted signal amplification[1].
Catechol(CT),resorcinol(RS) and hydroquinone(HQ) are three typical dihydroxybenzene isomers(DBIs).
Enzymatic inactivation is a main problem that can degrade the performance of biosensor.In order to resolve the problem,a new enzymatic immobilization carrier was developed by using biomimetic methods.
A 3D lanthanide metal-organic frameworks(Ln-MOFs) which possesses an open framework structure has been constructed.
Atmospheric pollution caused by the presence of nitrogenoxides(NOx) in the air,has been recognized as one of the mostserious environmental problem.
Continued consumption of fossil fuels and ever-increasing environmental issues have triggered extensive research attention on searching for renewable clean alternatives.
One-dimensional(1D)nanowires(NWs) with high surface area to volume ratio and lessagglomerated configuration are advantageous to accomplish highgas sensitivity and rapid response speed.
Carbon nanofibers(CNFs) are extremely attractive in bioanalytical area due to their unique properties of high surface area,non-toxicity and acceptable biocompatibility.
目前对于细颗粒物的仪器表征多关注其颗粒大小(粒径)和分布,而忽视了颗粒的形态(粒形).实际上,颗粒物的粒形与粒径同样重要,在颗粒物的性质和行为等多方面都起着重要的作用.颗粒的形态与颗粒的溶解度、流动性、渗透性、压缩性,体积和堆密度,沉淀率,静止角,聚敛率等都有关系[1,2].
随着工业化的快速发展,环境、食品污染问题日益严峻,常见污染物主要包括重金属、环境雌激素、生物毒素、致病菌、农/兽药残留、抗生素等,具有很强的致癌、致畸、致突变性,对水体、土壤、农田造成直接破坏和影响,对人类生存安全构成重大威胁.
