Silica coated Magnetic Nanoparticles (SMNPs): Capture and Identification of Escherichia coli Cells using Surface Enhanced Raman Spectroscopy

Rastogi S.K., Jabal J., Zhang H., Haler K.J., Gibson C.M., Qiang Y., Aston D.E., Hurdlicka P.J., Branen A.L., University of Idaho, US

Silica coated Magnetic nanoparticles (SMNPs; SiO2/Fe3O4 + Fe2O3) were prepared by encapsulation of iron oxide NPs with silica dioxide using the sol-gel method and characterized through transmission and scanning electron microscopic imaging, magnetic hysteresis and [...]

One Pot vs Two Steps Synthesis of Fluorescent Gold Nanoparticles and Capping with Thiolated Organic Linker

Rastogi S.K., Denn B.D., Branen A.L., University of Idaho, US

Nobel metal nanoparticles (NPs) such as Au and Ag have gained great attention in the past decades due to their fundamental optical properties. Based on that interest, the current work is focused for the synthesis [...]

Water Soluble Peroxyoamid Reagent: Evalulation for Fluorescent Silica Nano-Particles Chemilumineacence

Rastogi S.K., Fianaloski B., Mishra N.N., Cameron E., Bitterwolf T.E., Branen A.L., Maki W.C., University of Idaho, US

Chemiluminescence methods, both enzymatic and non-enzymatic, are widely used as an analytical tool in various bio-molecular detection applications. Advantages of using chemiluminscence detection are its practical simplicity, relatively low back ground interference, high sensitivity compared [...]

Amperometric Detection of Staphylococcal Enterotoxin B in milk using Magnetic Bead-Based Immunoassay on Disposable Screen Printed Carbon Electrode Strip

Rastogi S.K., Gibbon S., Branen A.L., Branen J.R., Branen A.L., Branen J.R., University of Idaho, US

A novel approach for the sensitive detection of Staphylococcal enterotoxin B (SEB) in milk is reported. The method used sandwich enzyme-linked immunoassay with SEB specific antibodies on magnetic beads. A small cylindrical magnet was fixed, [...]
