Transparent specimen is a unique method of biospecimen production, which was first used for scientific research purposes. After the death of the organisms, without destroying the integrity of the organisms, they are preserved in glycerol after being stained and made transparent using a variety of agents, including alcohol, potassium hydroxide, enzymes, and dyes. The structure of each organism is different, and the process of specimen production and the environment and other variables, each person will produce a different specimen, which is why each transparent biological specimen is unique in the world, just like you and me.
