Biological samples, things like hair, skin, and teeth, are really interesting to look at under a microscope. Biological systems are really complex and so much detail can be revealed using a microscope. Something like skin is especially interesting because it plays such an important role in our bodies and we can use it as a route to take medicines. The more we know about skin, the better we can design skin creams and soaps, for example – things we use everyday.
