Researchers around the world are racing to develop a vaccine against Covid-19, with more than 170 candidate vaccines now tracked by the World Health Organization (WHO).

Vaccines normally require years of testing and additional time to produce at scale, but scientists are hoping to develop a coronavirus vaccine within 12 to 18 months.

Vaccines mimic the virus – or part of the virus – they protect against, stimulating the immune system to develop antibodies. They must follow higher safety standards than other drugs because they are given to millions of healthy people.

Green Method to Make Nanoparticles and Ultrafine Powder

A novel freeze-dissolving approach has been devised that offers greater efficiency and sustainability compared to the classic freeze-drying process to make superfine powder or nanoparticles.​​​​​​​ In the research published in the journal ACS Sustainable Chemistry & Engineering, sphere-shaped [...]

Could gold nanoparticles help treat cancer?

Gold nanoparticles are minuscule particles made of gold. From drug and gene delivery to photothermal and photodynamic therapies to screening and diagnostic tests to radiation therapy, X-ray imaging and CT scans, these small particles [...]
