Biomarkers : biochemical indicators of exposure, response, and susceptibility to chemicals 2019 Kumar P, Kamboj M, Jaiwal R, Pundir CS

本研究制备了一种改进的安培型肌酐生物传感器,其核心是将肌酐酶(creatininase, CA)、肌酸酶(creatinase, CI)和肌氨酸氧化酶(sarcosine oxidase, SOx)分别制备成酶纳米颗粒(CANPs、CINPs、SOxNPs),并以共价方式固定于金电极(AuE)表面。通过扫描电子显微镜和循环伏安法对制...

Enzyme nanoparticles and their biosensing applications: A review.

Analytical biochemistry 2019 Neelam, Chhillar AK, Rana JS

酶纳米颗粒(ENPs)是酶分子在纳米尺度(10–100 nm)形成的聚集体,可经透射电镜(TEM)、傅里叶变换红外光谱(FTIR)、紫外-可见光谱、X射线衍射(XRD)、原子力显微镜(AFM)、扫描电镜(SEM)和电化学阻抗谱(EIS)表征。酶具有底物特异性、催化活性及温和条件下调控代谢反应的能力,但直接应用易降解,影响分析器件性能...

Development of glycerol biosensor based on co-immobilization of enzyme nanoparticles onto graphene oxide nanoparticles decorated pencil graphite electrode.

International journal of biological macromolecules 2019 Narwal V, Pundir CS

本研究通过共固定甘油激酶(GK)和甘油-3-磷酸氧化酶(GPO)纳米颗粒于氧化石墨烯纳米颗粒(GrONPs)修饰的铅笔石墨(PG)电极,构建了一种改进的安培型甘油生物传感器。GK纳米颗粒(GKNPs)、GPO纳米颗粒(GPONPs)和GrONPs经紫外光谱和透射电镜表征;工作电极(GKNPs/GPONPs/GrONPs/PGE)经扫...
