THE BI-SUBSTITUTED HYDROXYAPATITE AS RADIO-OPAQUE MATERIAL

Radio - opaque punctate

Dual functional selenium-substituted hydroxyapatite.

Hydroxyapatite (HA) doped with trace elements has attracted much attention recently owing to its excellent biological functions. Herein, we use a facile co-precipitation method to incorporate selenium into HA by adding sodium selenite during synthesis. The obtained selenium-substituted HA products are needle-like nanoparticles which have  size and crystallinity that are similar to those of the ...

Selection of tissue for microscopic study from lungs injected with radio-opaque material.

Choosing a suitable part of the lung by dissection distorts and often spoils the tissue for detailed histological study, especially when the peripheral part of the lung is concerned. These difficulties may be overcome by injecting the bronchial tree with radio-opaque material and choosing suitable areas from the abnormalities seen in a radiograph of the specimen. The parallax method is well sui...

Image transmission through an opaque material.

Optical imaging relies on the ability to illuminate an object, collect and analyse the light it scatters or transmits. Propagation through complex media such as biological tissues was so far believed to degrade the attainable depth, as well as the resolution for imaging, because of multiple scattering. This is why such media are usually considered opaque. Recently, we demonstrated that it is po...
