Imagine a tiny, revolutionary device that makes getting medicine or vaccines easier and more comfortable. That is the Micro Needle Drug Delivery System – a clever way to give drugs by gently piercing the skin’s outer layer. It consists of a microneedle and a drug patch, and the microneedles can even dissolve or break down. This innovation is a notable change in healthcare, especially for people who fear needles. It not only makes patients more comfortable but also lowers the risk of infections. These microneedles come in diverse types based on their use and materials. The only challenge is that they are super small and need careful handling to avoid staying under the skin. However, their convenience allows people to even administer medicines themselves. With a market set to grow from $1.0 billion in 2023 to $1.3 billion by 2028, at a steady rate of 5.1% each year, these microneedles are making a significant impact in the world of medicine.
