No more needles: Stanford scientists create a painless and alive vaccine that rubs the skin

Stanford scientists discovered that a harmless skin bacterium triggers a powerful immune response. By adjusting a bacterial protein, they made it a living vaccine, training the immune system to combat diseases such as tetanus and diphtheria. The mice administered this bioengineering bacteria developed a strong immunity, surviving doses of lethal toxins. With essays in humans…

Click the chemistry method advances the development of drugs with improved triazol synthesis

The proposed platform for triple click chemistry has three functional groups that can be attacked independently for replacement when choosing an appropriate reaction partner. This platform is compatible with sequential and versatile reactions of a single container that produce multi-triazols.
