Pilot Application of Magnetic Nanoparticle-Based Biosensor for Necrotizing Enterocolitis.
BACKGROUND Necrotizing Enterocolitis (NEC) is a major source of neonatal morbidity and mortality. There is an ongoing need for a sensitive diagnostic instrument to discriminate NEC from neonatal sepsis. We hypothesized that magnetic nanopartile-based biosensor analysis of gut injury-associated biomarkers would provide such an instrument. STUDY DESIGN We designed a magnetic multiplexed biosens...
متن کاملDevelopment of an Electrochemical-Based Aspartate Aminotransferase Nanoparticle Ir-C Biosensor for Screening of Liver Diseases
Aspartate aminotransaminase (AST) is a hepatocelluar enzyme released into the bloodstream when hepatic cells are damaged, resulting in elevated blood levels of AST. A single use, disposable biosensor prototype, composed of catalytic iridium nano-particles dispersed on carbon paste, was developed to detect enzymatically-produced H2O2 in AST-mediated reactions. This biosensor is capable of measur...
متن کاملUltrasensitive Magnetic Nanoparticle Detector for Biosensor Applications
Ta/Ru/Co/Ru/Co/Cu/Co/Ni80Fe20/Ta spin-valve giant magnetoresistive (GMR) multilayers were deposited using UHV magnetron sputtering and optimized to achieve a 13% GMR ratio before patterning. The GMR multilayer was patterned into 12 sensor arrays using a combination of e-beam and optical lithographies. Arrays were constructed with 400 nm × 400 nm and 400 nm × 200 nm sensors for the detection of ...
متن کاملDevelopment of an Electrochemical Biosensor for the Detection of Aflatoxin M1 in Milk
We have developed an electrochemical immunosensor for the detection of ultratrace amounts of aflatoxin M(1) (AFM(1)) in food products. The sensor was based on a competitive immunoassay using horseradish peroxidase (HRP) as a tag. Magnetic nanoparticles coated with antibody (anti-AFM(1)) were used to separate the bound and unbound fractions. The samples containing AFM(1) were incubated with a fi...
متن کاملDevelopment of biosensor based on immobilized L-glutamate oxidase for determination of monosodium glutamate in food.
A monosodium glutamate (MSG) biosensor with immobilized L-glutamate oxidase (L-GLOD) has been developed and studied for analysis of MSG in sauces, soup etc. The immobilized enzymatic membrane was attached with oxygen electrode with a push cap system. The detection limit of the sensor was 1 mg/dl and the standard curve was found to be linear upto 20 mg/dl. Response time of the sensor was 2 min. ...
