Bioconjugate chemistry is a specialised branch of science that deals with making connections between things made in the laboratory and things found in nature. You can think of it kind of like a big jigsaw puzzle. Scientists might take a special piece of a puzzle from the lab and use it to fit perfectly with a special piece already found in nature. Then, if scientists connect these pieces together carefully, it can be used for all kinds of things, like making medicines, new materials, and other important things.
