Hydroxyapatite

Hydroxyapatite is a form of calcium phosphate that has a large number of applications such as bone implants, and drug delivery systems. For each application, the use of calcium based materials is optimized by specifying their geometry, dimension, density, pore size, mechanical strength, purity, and chemical phase.

Electronic nose

The pictured shows a electronic sensors made of tin oxide nanowires grown on gold nanoparticles in monocrystalline silicon substrate. The "electronic nose" sensors based on semiconductor oxides gases are an industrial reality, and the subject of many investigations regarding new materials and sensor technology, data processing, interpretation and validation of results. It is a non-destructive technique used to characterize odorants in various applications related to quality of life, such as food control, the quality of the environment, public safety or clinical diagnosis.
