Dendrimers are highly branched, tree-like molecules that have a central core and multiple layers of repeating units called "branches." These structures are typically made from synthetic polymers and can be designed to have specific chemical properties, making them useful in various applications, including drug delivery and nanotechnology. Their unique shape allows for a high surface area, which can enhance interactions with other molecules. Due to their precise structure, dendrimers can encapsulate drugs and release them in a controlled manner, improving the effectiveness of treatments. Researchers are exploring their potential in fields like medicine, biotechnology, and materials science for applications such as targeted therapy and imaging.
