Ultrasensitive Detection of Nitrogen Oxides over a Nanoporous Membrane

Ultrasensitive cDNA Detection of Dengue Virus RNA Using Electrochemical Nanoporous Membrane-Based Biosensor

A nanoporous alumina membrane-based ultrasensitive DNA biosensor is constructed using 5'-aminated DNA probes immobilized onto the alumina channel walls. Alumina nanoporous membrane-like structure is carved over platinum wire electrode of 76 µm diameter dimension by electrochemical anodization. The hybridization of complementary target DNA with probe DNA molecules attached inside the pores influ...

Portable nanoporous electrical biosensor for ultrasensitive detection of Troponin-T

AIM To demonstrate the design, fabrication and testing of a portable, label-free biosensor for ultrasensitive detection of the cardiac Troponin-T (cTnT) from patient blood. MATERIALS & METHODS The biosensor is comprised of a nanoporous membrane integrated on to a microelectrode sensor platform for nanoconfinement effects. Charge perturbations due to antigen binding are recorded as impedance c...

Sources and chemistry of nitrogen oxides over the tropical Pacific

[1] We examine the sources and chemistry affecting nitrogen oxides (NOx=NO+NO2) over the tropical Pacific (30 S–20 N) using observations from the Pacific ExploratoryMission to the Tropics B (PEM-Tropics B) aircraft mission conducted in March–April 1999. A global model of tropospheric chemistry driven by assimilated meteorological data is used to interpret the observations. Median concentrations...

Control of Nitrogen Oxides

Plasma-induced nanoporous metal oxides with nitrogen doping for high-performance electrocatalysis.

The oxygen evolution reaction (OER) is a critical reaction in energy storage and conversion systems such as metal-air batteries and water splitting. The current commercial OER catalysts are the noble metal based materials, which have a high cost and a limited supply. Xu et al have prepared the nanoporous N-Co3O4 materials as cost-effective and high efficient electrocatalysts for OER by N2 plasm...
