Efficient removal of Cr (VI) and Cu (II) ions from aqueous media by use of polypyrrole/maghemite and polyaniline/maghemite magnetic nanocomposites
We examined the use of polypyrrole/maghemite (PPY/γ-Fe2O3) and polyaniline/maghemite (PANI/γ-Fe2O3) magnetic nanocomposites (MNCs) as active agents for removal of heavy metals ions from aqueousExpand

Impedimetric immunoassay for aflatoxin B1 using a cysteine modified gold electrode with covalently immobilized carbon nanotubes
AbstractThe authors describe a label-free electrochemical biosensor based on CNTs for picogram range detection of the food carcinogen aflatoxin B1 (AFB1). A gold electrode was modified with aExpand

Smartphone ownership and perspectives on health apps among a vulnerable population in East Harlem, New York.
Background Individuals from low-income and racial/ethnic minority backgrounds have traditionally had less access to mobile health (mHealth) technologies, but there is evidence that this gap has beenExpand

Impedimetric immunosensor for electronegative low density lipoprotein (LDL−) based on monoclonal antibody adsorbed on (polyvinyl formal)–gold nanoparticles matrix
Abstract Monoclonal antibodies (MAb) have been commonly applied to measure LDL in vivo and to characterize modifications of the lipids and apoprotein of the LDL particles. The electronegative lowExpand
