Evaluation of a Non-Enzymatic Electrochemical Sensor Based on Co(OH)-Functionalized Carbon Nanotubes for Glucose Detection.

This work reports on the assessment of a non-hydrolytic electrochemical sensor for glucose sensing that is developed using functionalized carbon nanotubes (fCNTs)/Co(OH). The morphology of the nanocomposite was investigated by scanning electron microscopy, which revealed that the CNTs interacted with Co(OH). This content formed a nanocomposite that improved the electrochemical characterizations of the electrode, including the electrochemical active surface area and capacitance, thus improving sensitivity to glucose.

Electrochemical Sensor for Hydrogen Peroxide Based on Prussian Blue Electrochemically Deposited at the TiO-ZrO-Doped Carbon Nanotube Glassy Carbon-Modified Electrode.

In this investigation, a hydrogen peroxide (HO) electrochemical sensor was evaluated. Prussian blue (PB) was electrodeposited at a glassy carbon (GC) electrode modified with titanium dioxide- and zirconia-doped functionalized carbon nanotubes (TiO.ZrO-fCNTs), obtaining the PB/TiO.

Colloid cysts of the third ventricle in children.

Objective: The rarity of colloid cysts in children makes it difficult to characterize this entity and offer meaningful advice on treatment. Infrequent case reports exist, but to date there has been no age-specific assessment. The purpose of this study was to define any differences between children and adults who are evaluated and treated for colloid cysts of the third ventricle.

Peroxide Electrochemical Sensor and Biosensor Based on Nanocomposite of TiO Nanoparticle/Multi-Walled Carbon Nanotube Modified Glassy Carbon Electrode.

A hydrogen peroxide (HO) sensor and biosensor based on modified multi-walled carbon nanotubes (CNTs) with titanium dioxide (TiO) nanostructures was designed and evaluated. The construction of the sensor was performed using a glassy carbon (GC) modified electrode with a TiO-CNT film and Prussian blue (PB) as an electrocalatyzer. The same sensor was also employed as the basis for HO biosensor construction through further modification with horseradish peroxidase (HRP) immobilized at the TiO-fCNT film.

Preserving and using germplasm and dissociated embryonic cells for conserving Caribbean and Pacific coral.

Coral reefs are experiencing unprecedented degradation due to human activities, and protecting specific reef habitats may not stop this decline, because the most serious threats are global (i.e., climate change), not local.
