Cholesterol oxidase (ChOx) has been immobilized onto zinc oxide (ZnO) nanoporous thin films grown on gold surface. A preferred c-axis oriented ZnO film with porous surface morphology fabricated by rf sputtering under high pressure. Optical studies and cyclic voltammetric measurements show that the ChOx∕ZnO∕Au bioelectrode is sensitive to detection of cholesterol in 25–400mg∕dl range. relatively low value enzyme’s kinetic parameter (Michaelis-Menten constant) ∼2.1mM indicates enhanced enzyme...
Glucose oxidase (GOx) has been covalently immobilized onto chemically synthesized thiolated gold nanoparticles (5−8 nm) via N-ethyl-N'-(3-dimethylaminopropyl) carbodiimide (EDC) and N-hydroxysuccinimide (NHS). The lower value of the Michaelis−Menton constant obtained for (3.74 mM) GOx compared with that free (5.85 suggests significant enhancement in activity attached to nanoparticles. exhibit a response time 30 s, shelf life more than 6 months, improved tolerance both pH temperature.
Abstract Nanomaterials, the building blocks of nanotechnology, possess important physical properties such as particle aggregation, photoemission, electrical and heat conductivities, chemical like catalytic activities. On basis unique properties, nanomaterials have received much attention from scientists researchers in different areas biomedical sciences biomolecule detection, sensing applications, gene delivery, clinical diagnostics, etc. This review focuses on types including their...
Two different kinds of CuO nanoparticles (NPs) namely nanorods (PS2) and multi-armed (P5) were synthesized by wet electrochemical routes, respectively. Their structure, morphology, size compositions characterized SEM, EDX XRD. The NPs demonstrated strong bactericidal potential against Bacillus anthracis cells endospores. PS2 killed 92.17% 4.5 × 10(4) CFU/mL B. within 1 h at a dose mg/mL. Whereas P5 showed higher efficacy killing 99.92% 7 10(5) 30 min 0.5 mg/mL 99.6% 1.25 5 2 More than 99%...
Vibrio cholerae, the aetiological agent of deadly diarrhoeal disease cholera, is known to form biofilm. The antibiotic susceptibility status biofilm V. cholerae O139, an important epidemic strain in India and other countries, has not previously been studied detail.Antibiotic planktonic cultures O139 was evaluated by determining MIC, MBC minimum eradication concentration (MBEC) values five different classes antibiotics using established methods. Effects treatment on were analysed scanning...
Abstract Nanostructures made up of restacked manganese oxide nanosheets and nanotubes were tested as reactive sorbents for the detoxification sulfur mustard, a highly persistent deadly chemical warfare agent. The kinetic data was compared with that precursor bulk H x MnO 2 material show agent undergoes hydrolysis elimination reactions yields hemisulfur thiodiglycol, chlorovinylethyl sulfide, divinyl hydroxyvinylethyl sulfide on surface adsorbent tubes; however, it oxidation reaction...
Enterohemorrhagic E. coil (EHEC) serotype O157:H7 is one of the major pathogens, responsible for severe disease outbreaks. EHEC causes diseases in humans through production shiga-like toxin leading to bloody diarrhea. The encoded by stx2 gene coli. current methodology detection relies on fluorogenic-substrate based culture media or nucleic acid amplification Real-Time Polymerase Chain Reaction assays that are either time consuming need expensive instrumentation. In this study, optical...

Abstract Mediator free enzyme sensor has been fabricated by covalently immobilizing cholesterol oxidase (ChOx) onto 11‐mercaptoundecanoic acid functionalized gold nanoparticles (MUDA‐AuNPs) – octadecylamine (ODA) hybrid Langmuir–Blodgett film. The cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) studies reveal that MUDA‐AuNP/ODA LB film good affinity for ChOx provides favorable microenvironment direct electron transfer between electrode. Interference estimation of...
