Summary

DescriptionMicropear.png	English: Crystallisation of hydroxyapatite (HAp) nanoparticles on Si-Ca-Na-P bioglass after immersion in simulated body fluid. In this case, HAp has formed as a pear-shaped microcrystal (~5 microns high), which even appears to have a bite taken out of it. By comparison, a human hair is ~100 microns thick. The bioglass was made by our novel rapid (200 times faster) sol-gel process. HAp is the main component of human bone. This bioglass can be used in biomedicine to make scaffolds or bio-implants to replace/regenerate damaged bone. (False colour, as this is an SEM image) Português: Cristalização de hidroxiapatita (HAp) nanopartículas no biovidro de Si-Ca-Na-P após imersão em fluido corporal simulado. Neste caso, HAp formou-se como um microcristal em forma duma pêra (~5 mícron de altura), que ainda parece ter uma mordida tirada dele. Em comparação, um cabelo humano é ~100 mícron de espessura. O biovidro foi feito pelo nosso novo rápido processo (200 vezes mais rápido) sol-gel. O HAp é o principal componente do osso humano. Este biovidro pode ser usado na biomedicina para fazer andaimes (scaffolds) ou bio-implantes para substituir/regenerar o osso danificado.
