Ion Selective Biosensors

Ion-selective biosensors are potentially useful in sensing Mg ion released based on hydrogen absorption. Hydrogen handling and elimination are important to prevent toxicity and pain from Mg-based implant degradation. For example, palladium has been studied for hydrogen sensing because it selectively absorbs hydrogen gas and forms a chemical species known as palladium hydride causing the metal lattice to expand by 3.5%. The principle of a hydrogen sensor lies in the fact that the palladium metal hydride's electrical resistance is greater than the metal's resistance. In such systems, the absorption of hydrogen is accompanied by a measurable increase in electrical resistance.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
