The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models suggest that mRNA vaccines prevented at least 14.4 million deaths from COVID-19 in the first year alone. Their extraordinary effectiveness in having … Read more
Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to spot early signs of cancer and other conditions using a simple blood test. Biomarkers such as proteins, DNA or other molecules can be used to … Read more

Hydrogels are polymeric materials with three-dimensional network structures containing large amounts of water. They serve as sustained-release drug delivery systems as they can encapsulate various bioactive substances, including drugs, antigens, and even cells. Hydrogels are better drug delivery alternatives than conventional systems, as they are more biocompatible, biodegradable, and easily administered as an injectable scaffold. … Read more
