Nanotechnology delivers hepatitis B vaccine

Publicado em 11 julho 2019
Brazilian and European researchers have demonstrated exactly how a nanotechnology-based compound delivers an oral vaccine against hepatitis B to the immune system. When particles containing silica and an antigen combine, even though they are different sizes, they reach the intestine without being destroyed by the acidity of the digestive system. A compound of nanostructured SBA-15 silica and HBsAg, the hepatitis B surface antigen, was submitted to different types of X-ray imaging in European [...]
