Counterfeit detector pens use a starch-iodine reaction to identify fake bills. But could you fool them with chemistry? In today's episode, we dive into the chemistry of iodine, its color and its clock reactions, all while making a little extra cash on the side. Let's say that we wanted to fool these counterfeit detection pens for science, how could we make this reaction not happen on normal paper?

Targeted radionuclide therapy (TRT) is gaining wide and rapid acceptance in clinical practice as it can deliver alpha or beta irradiation to a tumor-associated target which may be present in the tumor cell itself or in the microenvironment. The challenges related to this approach involve many biological aspects, such as determining the most reliable cellular or interstitial target and the most suitable vector able to carry the nuclide to the target, avoiding damage as much as possible with minimal detrimental effects on normal tissues.
